I was having the same problem but I could not run the above command, it got stuck with only a (I assume) non-relevant warning about a deprecated button use. Using aptitude it first gave me a warning about unable to update and propose several keeps, but after accepting the keeps it gave an other message about broken packages which it could fix. After this no keeps and it could do a normal update. After this, update still did not run but then I discovered there where mere update processes running at the same time. Killing them enabled me to run update and the problem is gone.
So for me the real problem looked to be the broken packages but unfortunately the broken packages were not logged and I have not noted them down. For the command line option to run it might give more info after killing the running update processes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1346414 Title: update-manager crashed with AttributeError in update(): 'NoneType' object has no attribute 'saveDistUpgrade' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1346414/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
