http://www.linuxquestions.org – I tried changing desktops (from xbuntu to Ubuntu; using the mythbuntu control center gui). During the switch, something didn't complete, now apt-get gives me this error in the history file: Start-Date: 2013-08-03 14:33:45 Commandline: apt-get -f install Install: xubuntu-default-settings:amd64 (12.04.11) Error: Sub-process /usr/bin/dpkg returned an error code (1) End-Date: 2013-08-03 14:33:47 How do I fix it?
