I installed 12.04 from the Update Manager. It was from 11.10. Afterwards, my computer said 'Restart Now.' So I did. Suddenly the computer froze, and my computer then said 'Ubuntu 12.04' in script font. It then went to typing in commands, and then, about 2 minutes later, it said:
Fixing Error But Reboot Is Required!!
So I rebooted. Everything went ok, I logged in ok, and now on the top bar it's saying:
''An error occurred, please run package manager from the right-click menu or run apt-get in a terminal to see what is wrong. The error message was: BrokenCount>0'. This usually means that your installed packages have unmet dependencies.''
What should I do? I don't want re-install 12.04.
