I recently upgraded my system from 15.10 to 16.04 using the
do-release-upgrade command. The upgrade failed for an unknown reason and now the Ubuntu Desktop does not load. I get my desktop wallpaper and my icons but nothing else. It is however detecting both my monitors correctly. I'm guessing that there is a package that needs to be updated since the command line states 16.04 but the login screen still states 15.10. Does anyone have an idea how to rectify the issue?
