update-manager crashed with RuntimeError in __main__: could not open display

[Andrey Serdyukov]

Binary package hint: update-manager

So I logged in Ubuntu 11.04, but there were no Unity or any other menus, only icons on desctop and nothing else. So I pressed ctrl+alt+f2 and typed in sudo update-manager, but there were bunch of errors, so I pressed cttrl+alt+f7 to go back to my desktop, however crash thing appeared telling me that update-manger can not be started and crashed.
