I recently use the command sudo apt-get update in Ubuntu 14.04 and now when I want install packages, I get an error.

For example, when I use sudo apt-get install vagrant for installing Vagrant I get the following error:

invoke-rc.d: initscript cups, action "start" failed.
dpkg: error processing package cups-daemon (--configure):
subprocess installed post-installation script returned error exit status 1
Setting up fontconfig (2.11.1-0ubuntu6) ...
Regenerating fonts cache... failed.
See /var/log/fontconfig.log for more information.
dpkg: error processing package fontconfig (--configure):

E: Sub-process /usr/bin/dpkg returned an error code (1)

I have searched for details about this error, and one person suggested using sudo apt-get upgrade. I tried this, but it does not help.

How can I fix this problem?

It means you added a bad source.list and your libraries became corrupt due it. In my case I had added source list of 13.04 in ubuntu 14.04 to make somethings work based on the answer of some guy in askubuntu.com, that was the stupidest thing I did, and learnt never to add libraries of older versions. But it did solve the problem and everything was working fine until I restarted the system.

When I got this error, I restarted by ubuntu and I was unable to start it again. Reboot failed. So I took a pendrive and upgraded the 14.04 to 16.04 and everything was fixed and I was able to install this cup thing too. That was the only thing I could do.

So use:

sudo apt-get upgrade
