How to clean /var/cache?












13















When I woke up this morning, I found my root had filled overnight



du -hx --max-depth=1 /

132M /boot
4.0K /media
16K /lost+found
16M /root
702M /lib
4.0K /OLDHOME
8.2G /usr
73M /etc
4.0K /srv
11M /sbin
4.0K /selinux
8.0K /.config
4.0K /cdrom
4.6G /var
181M /opt
4.0K /mnt
9.3M /bin
4.0K /lib64
14G /


The space is used by /var/cache/polipo (2.7G). How can I clean this up safely?

I tried restarts=>didn't work

Used bleachbit=>the space is not detected in the cleanup preview



PS: I did rm -rf youtube inside /var/cache/polipo and it freed up 2G space. Dunno if it was safe though

Polipo, a web caching program may store a lot of data in an on-disk cache.



One way to clear this up is to issue the command sudo polipo -x - this will cause polipo to clear the local disk cache.

It sounds so obvious, and yet chances are you haven’t done this.



By default Ubuntu keeps every update it downloads and installs in a cache on your disk, just in case you ever need it again.



This is useful if you regularly add and remove apps, find yourself needing to reconfigure/reinstall a specific package, or simply have a poor connection.



But the flip side is that the apt package cache can quickly swell to several hundred MBs. This command tells you how big your apt cache is:



du -sh /var/cache/apt/archives



To clean the apt cache on Ubuntu simply run the following command.



sudo apt-get clean



The apt clean command removes ALL packages kept in the apt cache, regardless of age or need. If you’re on a slow, capped or intermittent connection you may want to consider skipping this step.
