update-manager crashed with ImportError in __main__: No module named UpdateManager.UpdateManager

[Kenneth Wrede]

Chrashed when I tried to view the available updates, using the panel in quantal xubuntu, xfce 4.10. Previously I have updated everthing except the new kernel that couldn't be fetched. What should have been viewed is linux-generic and it's header package. (I hope this is relevant.)

Looking at /usr/bin/update-manager it uses #! /usr/bin/python but the UpdateManager python code is in /usr/lib/python3/dist-packages. It does run changing the shebang to /usr/bin/python3, though quickly glancing at the changelog I can't tell if the python3 port is complete yet, so may cause other issues.

Actually, looks like this was just fixed in 1:0.167 (sudo apt-get update; sudo apt-get upgrade; to work around the issue until you can use update-manager again). Marking this as a dup of bug #1023474
