I just upgraded from 12.04 to 14.04 and i kept getting stuck at the splash screen. I turned off quiet splash and it seems to be hanging after "Restoring resolver state..."
The only solution I've been able to find is to re-install Ubuntu, but i really do not want to have to do that!
I have still not solved this issue and it is quite frustrating. Is there something I can do to give more information?
