I'm running Ubuntu 12.04 (32-bit). I manually installed Adoble Flash Player 9 from the software center. The problem now is that the system is not running as it used to. Whenever I click on "software center" the screen goes blank and the start menu does not even let me find programmes. For example, the terminal cannot be found and I can only find it with the hotkeys. No other programmes are to be found.
How could I completely remove Adobe Flash Player? Would that be the solution? Thank you.
