Ubuntu 14.04 and above



The apt tool on Ubuntu 14.04 and above makes this very easy.



apt list --installed




Older Versions



To get a list of packages installed locally do this in your terminal:





dpkg --get-selections | grep -v deinstall


(The -v tag "inverts" grep to return non-matching lines)



To get a list of a specific package installed:



dpkg --get-selections | grep postgres


To save that list to a text file called packages on your desktop do this in your terminal:



dpkg --get-selections | grep -v deinstall > ~/Desktop/packages


Alternatively, simply use



dpkg -l


(you don't need to run any of these commands as the superuser, so no sudo or any other variants necessary here)

    Then, when installing to the new computer, do cat ~/Desktop/packages > sudo dpkg --set-selections && sudo apt-get dselect upgrade source

    The syntax for dpkg may have changed slightly since 2006 because that command didn't work for me, @koanhead. sudo dpkg --set-selections < ~/Desktop/packages && sudo apt-get -u dselect-upgrade does the trick.

    Note that this won't keep track of which packages were explicitly installed by the user and which were installed as dependencies. This means that if you use this method to recreate your setup on another machine, apt won't be able to remove unneeded dependencies when you remove a given package.

    It's sad and amazing that @intuited 's comment is not better understood by the community. Would the more "highly rated" contributors stop to think more before giving the advice that simply reloading old packages on a new ubuntu version is not a good idea(?). With all the dpkg options I still do not see one that pulls out the 'expressely' installed packages by a user in order that THAT list can be reloaded and allowed to have its dependencies installed; I would love to know it - please share that info. In the meantime, make a list of the packages you really need on a re-install and run that

To get just the packages which were expressly installed (not just installed as dependencies), you can run



aptitude search '~i!~M'


This will also include a brief description, which you may want. If not, also add the option -F '%p', as mentioned by karthick87.





Yet another option seems to be to copy the file /var/lib/apt/extended_states, which is a text file database in this format:



Package: grub-common
Architecture: amd64
Auto-Installed: 0

Package: linux-headers-2.6.35-22-generic
Architecture: amd64
Auto-Installed: 1


Auto-Installed: 0 indicates that the package was expressly installed and is not just a dependency.

    This should be the answer, but using aptitude is a bit unreliable because of Multiarch currently (fixes on the way), unfortunately. Still +1 for pointing out only listing explicitly installed packages and a way to do this (despite it won't work on 11.10+ currently).

Create a backup of what packages are currently installed:



dpkg --get-selections > list.txt


Then (on another system) restore installations from that list:



dpkg --clear-selections
sudo dpkg --set-selections < list.txt


To get rid of stale packages:



sudo apt-get autoremove


To get installed like at backup time (i.e. to install packages set by dpkg --set-selections):



sudo apt-get dselect-upgrade

    And sometimes system updates an app that you specifically wish system to not touch it ever, do fire this at end of commands sudo apt-mark hold name-your-package . This will prevent apt-get from upgrading to current version which is the default for updating process.

To list all packages intentionally installed (not as dependencies) by apt commands, run the following :



(zcat $(ls -tr /var/log/apt/history.log*.gz); cat /var/log/apt/history.log) 2>/dev/null |
egrep '^(Start-Date:|Commandline:)' |
grep -v aptdaemon |
egrep '^Commandline:'




This provides a reverse time based view, with older commands listed first:



Commandline: apt-get install k3b
Commandline: apt-get install jhead
...




Installation data also showing synaptic usage, but without details
(the same with installation date) :



(zcat $(ls -tr /var/log/apt/history.log*.gz); cat /var/log/apt/history.log) 2>/dev/null |
egrep '^(Start-Date:|Commandline:)' |
grep -v aptdaemon |
egrep -B1 '^Commandline:'


providing the following:



Start-Date: 2012-09-23  14:02:14
Commandline: apt-get install gparted
Start-Date: 2012-09-23 15:02:51
Commandline: apt-get install sysstat
...

    Or (with zgrep and removing update messages): zgrep -hE '^(Start-Date:|Commandline:)' $(ls -tr /var/log/apt/history.log*.gz ) | egrep -v 'aptdaemon|upgrade' | egrep -B1 '^Commandline:'

    While the above simple answers are good for the general user. This method by far is the best for backtracking all the customizations done to the machine, as it also shows what was removed, or added, from the base image, as it list them in the sequence it was performed, and helps you remember which is the correct sequence to add them back in another system.

apt-mark showmanual


man pages state:




will print a list of manually installed packages




So, it should just give a list of explicitly installed packages (though this includes packages that were part of the default initial install) without all of the dependencies included due to these packages being installed.



To output the result into a text file:



apt-mark showmanual > list-manually-installed.txt

    Well the question was for installed packages and this gives all installed packages minus the automatically installed dependencies. It does include the initial packages as part of the initial install. I guess you could run this on a fresh install to get a list of the default installs and then subtract that from this to see the difference.

dpkg-query (instead of dpkg --get-selections, which lists some packages that are not installed) as follows:

To list all installed packages,



dpkg -l |awk '/^[hi]i/{print $2}' > 1.txt


or



aptitude search -F '%p' '~i' > 1.txt


or



dpkg --get-selections > 1.txt


Note:

You will get the result 1.txt file in your home folder or you can specify your own path.

    You can use Synaptic to save the current state of your installed packaged. In Synaptic, select "file/save markings", Enter the name of the file to save the state to, and make sure to check the "Save full state, not only changes" box.



    The file saved from this can be loaded into a new machine using "file/read markings" in Synaptic.

      I recommend using blueprint. Even though it is designed for servers, it can be also used from desktops as well. It will create a shell script/chef/puppet that you ca use to re-install all you packages.

      You want to reinstall the packages now there on 12.04, right?



      If so, it's very easy. You'll need an "Ubuntu Single Sign On account." (Create it before reinstalling so that your system is synced.)




      1. Go to the Software Center and look for the "Sync Between Computers..." option under the File menu.


      2. When you click on it you will see your computer registered and a list of all apps on your computer.


      3. When you will install fresh, that computer will be considered a new computer.


      4. You just have to sign in to your Ubuntu account and your previous computer will be shown.


      5. Click on it; you'll get a list of all apps. Select "install" on the app you want to install.

      There's also a tool called Aptik (both command line and GUI) which can help you view a list of all installed packages, with an option to select/unselect some of them, make a backup list, and then restore the same set of packages in another system.



      To install:



      sudo add-apt-repository -y ppa:teejee2008/ppa
      sudo apt-get update
      sudo apt-get install aptik


      Further info: http://www.teejeetech.in/2014/04/aptik-v14.html



      enter image description here



      As can be seen in the screenshot, Aptik lets you also backup and restore PPAs, which will certainly be necessary to install some of the packages installed.

      APT-Clone. This package can be used to clone/restore the packages on a apt based system.




      • It will save/restore the packages, sources.list, keyring and
        automatic-installed states.

      • It can also save/restore no longer downloadable packages using dpkg-repack.


      source: man apt-clone




      APT-Clone is used by ubiquity (Ubuntu installer) for upgrade process. It is much better than the dpkg --get-selections solution because:




      1. It preserves all repositories information.

      2. It keeps track of what packages were automatically installed.

      3. It allows to repack locally installed DEB files.


      How to Use





      1. Install



        sudo apt-get install apt-clone



      2. Make backup



        sudo apt-clone clone path-to/apt-clone-state-ubuntu-$(lsb_release -sr)-$(date +%F).tar.gz



      3. Restore backup



        sudo apt-clone restore path-to/apt-clone-state-ubuntu.tar.gz


        Restore to newer release:



        sudo apt-clone restore-new-distro path-to/apt-clone-state-ubuntu.tar.gz $(lsb_release -sc)



      It make simple gzipped tar file which can be easily edited and reviewed before restoring on the other machines. Here an example of its structure:



      /
      ├── etc
      │   └── apt
      │   ├── preferences.d

        There's a great explanation on Unix StackExchange that describes how to use aptitude to list packages not installed as dependencies, and how to compare that list with the list of default packages for your Ubuntu release.



        To obtain the manifest file for desktop versions of 12.04 and newer, visit this site, choose your release, and scroll down below the CD images to the files section. You'll find something like "ubuntu-12.04.4-desktop-amd64+mac.manifest" that matches your architecture.



        For server versions you'll need to obtain the manifest file from the ISO that was used to install the original system. For a VPS or cloud server, your provider may make the images available or you might need to contact them.



        Here's an example using the code from the referenced post, along with modifications to install on the new server.



        Old server (code from other post, output saved to file):



        aptitude search '~i !~M' -F '%p' --disable-columns | sort -u > currently-installed.list
        wget -qO - http://mirror.pnl.gov/releases/precise/ubuntu-12.04.3-desktop-amd64.manifest
        | cut -f1 | sort -u > default-installed.list
        comm -23 currently-installed.list default-installed.list > user-installed.list


        On the new server, copy the file using scp, then use sed to append 'install' to every line (-i performs an inline-replace). Then you can use the list as input to 'dpkg --set-selections' and install the packages with apt-get:



        scp user@oldserver:user-installed.list .
        sed -i 's/$/tinstall/' user-installed.list
        sudo dpkg --set-selections < user-installed.list
        sudo apt-get dselect-upgrade


        Before starting this task, I recommend reading and understanding all parts of the post mentioned in the beginning, and then consult the aptitude reference guide for details on search patterns.

          You can look at the apt log under /var/log/apt/ and the dpkg log under /var/log/



          and you can get the list of the installed packages with just a command:



          dpkg -l | grep '^ii '

              TLDR; I eventually found that apt --installed listgives best result (as suggested in top answer above. Although apt-cache pkgnames seems to do the trick at first glance, it lists "all packages in the system" (per the help text above), which also includes packages which apt knows about but aren't actually installed. There's a --installed option but it doesn't seem to work with pkgnames.

              apt-cache pkgnames | wc -l gives 55909 packages (the system knows about), whereas aptitude search '~i!~M' | wc -l gives 2160 (packages explicitly installed, without dependencies).

              • The .1 there implies the log was rotated, if that's the case then maybe it's better to grep /var/log/dpkg.log* to get all rotated logs.

                dpkg, xargs, & apt-get



                This command should accomplish the creation of a text file containing installed packages:



                dpkg -l | awk  '{print $2}' > package_list.txt


                To accomplish the bulk installation of the listed packages you'll need to edit 'package_list.txt'. Remove the weird lines at the top of the file using a text editor. You can then use this command to install packages from the created file using:



                xargs < package_list.txt apt-get install -y




                apt-cache, xargs, & apt-get



                Only use this method if you want all current packages to be installed using the list (which includes automatically installed, etc).



                Output the response of 'apt-cache pkgnames' to a file we'll simply name "package_list.txt". You can accomplish this with:



                apt-cache pkgnames > package_list.txt


                Then when you want to install packages from "package_list.txt" you would use this command:



                xargs < package_list.txt apt-get install -y




                apt-mark, xargs, & apt-get



                We can use the command apt-mark showmanual to give a list of packages that were manually or initially installed with Ubuntu. We'll want to output that to a file we'll just call "package-list.txt". Use this command to accomplish that:



                apt-mark showmanual > package-list.txt


                The command we would use to install packages from the file "package_list.txt" is below.



                xargs < package_list.txt apt-get install -y

                2














                1. List the installed software packages on Ubuntu



                To list the installed software packages on your machine you can use the following command:



                sudo apt list --installed


                The output of the command will be very similar to the following one, depending on which packages are currently installed:



                Listing...
                acl/xenial,now 2.2.52-3 amd64 [installed]
                adduser/xenial,xenial,now 3.113+nmu3ubuntu4 all [installed]
                apache2/xenial-updates,xenial-security,now 2.4.18-2ubuntu3.1 amd64 [installed]
                apache2-bin/xenial-updates,xenial-security,now 2.4.18-2ubuntu3.1 amd64 [installed,automatic]
                apache2-data/xenial-updates,xenial-updates,xenial-security,xenial-security,now 2.4.18-2ubuntu3.1 all [installed,automatic]
                apache2-doc/xenial-updates,xenial-updates,xenial-security,xenial-security,now 2.4.18-2ubuntu3.1 all [installed]
                apache2-utils/xenial-updates,xenial-security,now 2.4.18-2ubuntu3.1 amd64 [installed]
                apparmor/xenial-updates,now 2.10.95-0ubuntu2.5 amd64 [installed,automatic]
                apt/xenial-updates,now 1.2.19 amd64 [installed]
                apt-utils/xenial-updates,now 1.2.19 amd64 [installed]
                ...


                2. Use the LESS program



                To easily read the entire output you can use the less program.



                sudo apt list --installed | less


                3. Use the GREP Command



                You can look for a specific package through the output using the grep program.



                sudo apt list --installed | grep -i apache


                4. List all packages that include Apache



                The output from the above command will list all packages that include apache in their names.



                apache2/xenial-updates,xenial-security,now 2.4.18-2ubuntu3.1 amd64 [installed]
                apache2-bin/xenial-updates,xenial-security,now 2.4.18-2ubuntu3.1 amd64 [installed,automatic]
                apache2-data/xenial-updates,xenial-updates,xenial-security,xenial-security,now 2.4.18-2ubuntu3.1 all [installed,automatic]
                apache2-doc/xenial-updates,xenial-updates,xenial-security,xenial-security,now 2.4.18-2ubuntu3.1 all [installed]
                apache2-utils/xenial-updates,xenial-security,now 2.4.18-2ubuntu3.1 amd64 [installed]
                libapache2-mod-php/xenial,xenial,now 1:7.0+35ubuntu6 all [installed,automatic]
                libapache2-mod-php7.0/xenial-updates,now 7.0.13-0ubuntu0.16.04.1 amd64 [installed,automatic]
                libapache2-mod-security2/xenial,now 2.9.0-1 amd64 [installed]
                libapache2-modsecurity/xenial,xenial,now 2.9.0-1 all [installed]


                Apt supports patterns to match package names and options to list installed (--installed) packages, upgradeable (--upgradeable) packages or all available (--all-versions) package versions.



                5. Use the DPKG program



                Another alternative that you can use to list the installed software packages on your Ubuntu VPS is the dpkg command.



                sudo dpkg -l


                The output of the command will provide you with information such as the name of the package, version, architecture and short description about the package. Of course, you can use the grep program again to search for a specific package.



                sudo dpkg -l | grep -i apache


                The output should look like the one below:



                ii  apache2                       2.4.18-2ubuntu3.1                     amd64        Apache HTTP Server

                  I think it is interesting to note apt list --installed or dpkg-query --list actually use the file called /var/lib/dpkg/status in behind where all the info about the packages is beard.



                  So if you would like to deal with the super extended list of packages just cat /var/lib/dpkg/status.



                  Note: Do not alter /var/lib/dpkg/status file.

                    The package dctrl-tools provide the grep-status tool to get the list of the packages marked as installed on your system:



                    sudo apt install dctrl-tools


                    Usage:



                    grep-status -FStatus -sPackage -n   "install ok installed"

                      There are many ways to do that. In case you are using CentOS like me you can use these:
                      1. yum list installed
                      2. rpm -qa

                          Note that this won't keep track of which packages were explicitly installed by the user and which were installed as dependencies. This means that if you use this method to recreate your setup on another machine, apt won't be able to remove unneeded dependencies when you remove a given package.

Would the more "highly rated" contributors stop to think more before giving the advice that simply reloading old packages on a new ubuntu version is not a good idea(?). With all the dpkg options I still do not see one that pulls out the 'expressely' installed packages by a user in order that THAT list can be reloaded and allowed to have its dependencies installed; I would love to know it - please share that info. In the meantime, make a list of the packages you really need on a re-install and run that

                          Note that this won't keep track of which packages were explicitly installed by the user and which were installed as dependencies. This means that if you use this method to recreate your setup on another machine, apt won't be able to remove unneeded dependencies when you remove a given package.

                          It's sad and amazing that @intuited 's comment is not better understood by the community. Would the more "highly rated" contributors stop to think more before giving the advice that simply reloading old packages on a new ubuntu version is not a good idea(?). With all the dpkg options I still do not see one that pulls out the 'expressely' installed packages by a user in order that THAT list can be reloaded and allowed to have its dependencies installed; I would love to know it - please share that info. In the meantime, make a list of the packages you really need on a re-install and run that

                          We all know that linux discriminates people without photographic memory, but seriously, what would be wrong with apt list installed. Someday we should stop systematically failing the "keep simple things easy" principle.

                        The apt tool on Ubuntu 14.04 and above makes this very easy.



                        apt list --installed




                        Older Versions



                        To get a list of packages installed locally do this in your terminal:





                        dpkg --get-selections | grep -v deinstall


                        (The -v tag "inverts" grep to return non-matching lines)



                        To get a list of a specific package installed:



                        dpkg --get-selections | grep postgres


                        To save that list to a text file called packages on your desktop do this in your terminal:



                        dpkg --get-selections | grep -v deinstall > ~/Desktop/packages


                        Alternatively, simply use



                        dpkg -l


                        (you don't need to run any of these commands as the superuser, so no sudo or any other variants necessary here)

                        392














                        To get just the packages which were expressly installed (not just installed as dependencies), you can run



                        aptitude search '~i!~M'


                        This will also include a brief description, which you may want. If not, also add the option -F '%p', as mentioned by karthick87.





                        Yet another option seems to be to copy the file /var/lib/apt/extended_states, which is a text file database in this format:



                        Package: grub-common
                        Architecture: amd64
                        Auto-Installed: 0

                        Architecture: amd64
                        Auto-Installed: 1


                        Auto-Installed: 0 indicates that the package was expressly installed and is not just a dependency.

                          This should be the correct answer. Why list dependencies?

                          This should be the answer, but using aptitude is a bit unreliable because of Multiarch currently (fixes on the way), unfortunately. Still +1 for pointing out only listing explicitly installed packages and a way to do this (despite it won't work on 11.10+ currently).

                        To get just the packages which were expressly installed (not just installed as dependencies), you can run



                        aptitude search '~i!~M'


                        This will also include a brief description, which you may want. If not, also add the option -F '%p', as mentioned by karthick87.





                        Yet another option seems to be to copy the file /var/lib/apt/extended_states, which is a text file database in this format:



                        Package: grub-common
                        Architecture: amd64
                        Auto-Installed: 0

                        Package: linux-headers-2.6.35-22-generic
                        Architecture: amd64
                        Auto-Installed: 1


                        Auto-Installed: 0 indicates that the package was expressly installed and is not just a dependency.

                          This should be the correct answer. Why list dependencies?

                          This should be the answer, but using aptitude is a bit unreliable because of Multiarch currently (fixes on the way), unfortunately. Still +1 for pointing out only listing explicitly installed packages and a way to do this (despite it won't work on 11.10+ currently).

                        Create a backup of what packages are currently installed:

                          migrating between 2 different ubuntu 12.04 machines this approach broke my system. it took a while until I realized that somehow ubuntu-desktop got uninstalled - probably due to one of the dpkg commands. be careful, it took me hours to repair the damage!

                          And sometimes system updates an app that you specifically wish system to not touch it ever, do fire this at end of commands sudo apt-mark hold name-your-package . This will prevent apt-get from upgrading to current version which is the default for updating process.

                          migrating between 2 different ubuntu 12.04 machines this approach broke my system. it took a while until I realized that somehow ubuntu-desktop got uninstalled - probably due to one of the dpkg commands. be careful, it took me hours to repair the damage!

                          And sometimes system updates an app that you specifically wish system to not touch it ever, do fire this at end of commands sudo apt-mark hold name-your-package . This will prevent apt-get from upgrading to current version which is the default for updating process.

                        182














                        To list all packages intentionally installed (not as dependencies) by apt commands, run the following :



                        (zcat $(ls -tr /var/log/apt/history.log*.gz); cat /var/log/apt/history.log) 2>/dev/null |
                        egrep '^(Start-Date:|Commandline:)' |
                        grep -v aptdaemon |
                        egrep '^Commandline:'




                        This provides a reverse time based view, with older commands listed first:



                        Commandline: apt-get install k3b
                        Commandline: apt-get install jhead
                        ...




                        Installation data also showing synaptic usage, but without details
                        (the same with installation date) :



                        (zcat $(ls -tr /var/log/apt/history.log*.gz); cat /var/log/apt/history.log) 2>/dev/null |
                        egrep '^(Start-Date:|Commandline:)' |
                        grep -v aptdaemon |
                        egrep -B1 '^Commandline:'


                        providing the following:



                        Start-Date: 2012-09-23  14:02:14
                        Commandline: apt-get install gparted
                        Start-Date: 2012-09-23 15:02:51
                        Commandline: apt-get install sysstat

                          While the above simple answers are good for the general user. This method by far is the best for backtracking all the customizations done to the machine, as it also shows what was removed, or added, from the base image, as it list them in the sequence it was performed, and helps you remember which is the correct sequence to add them back in another system.

                                        You want to reinstall the packages now there on 12.04, right?



                                        If so, it's very easy. You'll need an "Ubuntu Single Sign On account." (Create it before reinstalling so that your system is synced.)




                                        1. Go to the Software Center and look for the "Sync Between Computers..." option under the File menu.


                                        2. When you click on it you will see your computer registered and a list of all apps on your computer.


                                        3. When you will install fresh, that computer will be considered a new computer.


                                        4. You just have to sign in to your Ubuntu account and your previous computer will be shown.


                                        5. Click on it; you'll get a list of all apps. Select "install" on the app you want to install.

                                        There's also a tool called Aptik (both command line and GUI) which can help you view a list of all installed packages, with an option to select/unselect some of them, make a backup list, and then restore the same set of packages in another system.



                                        To install:



                                        sudo add-apt-repository -y ppa:teejee2008/ppa
                                        sudo apt-get update
                                        sudo apt-get install aptik


                                        Further info: http://www.teejeetech.in/2014/04/aptik-v14.html



                                        enter image description here



                                        As can be seen in the screenshot, Aptik lets you also backup and restore PPAs, which will certainly be necessary to install some of the packages installed.

                                                There's a great explanation on Unix StackExchange that describes how to use aptitude to list packages not installed as dependencies, and how to compare that list with the list of default packages for your Ubuntu release.



                                                To obtain the manifest file for desktop versions of 12.04 and newer, visit this site, choose your release, and scroll down below the CD images to the files section. You'll find something like "ubuntu-12.04.4-desktop-amd64+mac.manifest" that matches your architecture.



                                                For server versions you'll need to obtain the manifest file from the ISO that was used to install the original system. For a VPS or cloud server, your provider may make the images available or you might need to contact them.



                                                Here's an example using the code from the referenced post, along with modifications to install on the new server.



                                                Old server (code from other post, output saved to file):



                                                aptitude search '~i !~M' -F '%p' --disable-columns | sort -u > currently-installed.list
                                                wget -qO - http://mirror.pnl.gov/releases/precise/ubuntu-12.04.3-desktop-amd64.manifest
                                                | cut -f1 | sort -u > default-installed.list
                                                comm -23 currently-installed.list default-installed.list > user-installed.list


                                                On the new server, copy the file using scp, then use sed to append 'install' to every line (-i performs an inline-replace). Then you can use the list as input to 'dpkg --set-selections' and install the packages with apt-get:



                                                scp user@oldserver:user-installed.list .
                                                sed -i 's/$/tinstall/' user-installed.list
                                                sudo dpkg --set-selections < user-installed.list
                                                sudo apt-get dselect-upgrade


                                                Before starting this task, I recommend reading and understanding all parts of the post mentioned in the beginning, and then consult the aptitude reference guide for details on search patterns.

Remove the weird lines at the top of the file using a text editor. You can then use this command to install packages from the created file using:

We'll want to output that to a file we'll just call "package-list.txt". Use this command to accomplish that:

                                                                                xargs < package_list.txt apt-get install -y

                                                                                Only use this method if you want all current packages to be installed using the list (which includes automatically installed, etc).



                                                                                Output the response of 'apt-cache pkgnames' to a file we'll simply name "package_list.txt". You can accomplish this with:



                                                                                apt-cache pkgnames > package_list.txt

We'll want to output that to a file we'll just call "package-list.txt". Use this command to accomplish that:



                                                                                apt-mark showmanual > package-list.txt

                                                                                sudo apt list --installed | grep -i apache

                                                                                5. Use the DPKG program

                                                                                sudo dpkg -l

Of course, you can use the grep program again to search for a specific package.



                                                                                sudo dpkg -l | grep -i apache

                                                                                  5. Use the DPKG program

                                                                                  sudo dpkg -l

Of course, you can use the grep program again to search for a specific package.



                                                                                  sudo dpkg -l | grep -i apache

                                                                                    The output of the command will provide you with information such as the name of the package, version, architecture and short description about the package. Of course, you can use the grep program again to search for a specific package.



                                                                                    sudo dpkg -l | grep -i apache


                                                                                    The output should look like the one below:
