Comment 17 for bug 574244

@Arvid: my system was not in a broken state although it reported a "partial upgrade" some boot operations later. So I followed the proposed "upgrade" and the system was upgraded once more. I don't know what it did there exactly but it was similar to the normal upgrade process. It just didn't take a long time because all the packages were upgraded already.

The "cleanup" can mostly be done manually using "System → Administration → Computer Janitor" (don't know the program name in Swedish though).
