I can't install/remove/resolve the problem caused by libnss3 on my ubuntu 14.04.4 LTS. At the beginning I got a problem on Upwork time tracker (Connection failed) then I followed the steps on this link:https://gist.github.com/alexda14/d0632aed2fbf86c6fee1. then the libnss3 packages messed up my machine. It says 'Error:BrokenCount > 0. this usually means that your installed packages have unmet dependencies'. I've tried everything to solve the conflicts issued but fail.

sudo dpkg --audit

The following packages have been unpacked but not yet configured.

They must be configured using dpkg --configure or the configure

menu option in dselect for them to work:

 libnss3-1d:i386      Network Security Service libraries - transitional package

 libnss3:i386         Network Security Service libraries



The following packages are only half configured, probably due to problems

configuring them the first time.  The configuration should be retried using

dpkg --configure <package> or the configure menu option in dselect:

 libnss3:amd64        Network Security Service libraries

then

sudo dpkg --configure -a

dpkg: dependency problems prevent configuration of libnss3-1d:i386:

 libnss3-1d:i386 depends on libnss3 (= 2:3.21-0ubuntu0.14.04.1); however:

  Version of libnss3:i386 on system is 2:3.19.2-1ubuntu1.

Okay. I managed to fix my problem. Actually it my own mistakes. I have 64bit ubuntu but installed libnss3 for i386.

apt-cache policy libnss3*

to find out all libnss3 dependencies then purge them:

sudo apt-get purge libnss3-1d:i386 libnss3-nssdb:i386 libnss3-1d-dbg:i386 libnss3-dbg:i386 libnss3:i386 libnss3-dev:i386 libnss3-tools:i386
