Upgrade to 12.04.1 (from 10.04) seemed to go smoothly. After the upgrade was finished and i restarted the server i am automatically logged out as soon as i log in. I get the welcome message with load and memory usage, etc, but then it immediately logs the user out. Logging in over SSH does the same thing.
Searched a bit and find some people with similar problems, mostly related to the desktop environment. I'm not running a desktop or graphical environment at all.
I can log into the administrator mode for cups and it recognizes user credentials, but i can't ssh or physically log into the server.
Anyone have any ideas?
