I just upgraded my Ubuntu 11.10 to 12.04 after the announcement of the final release of Ubuntu 12.04. The upgrade process went fine.
But now when I run the update manager it asks for a partial upgrade. But the funny thing is it installs 84 new packages in installation step, remove all the 84 packages in the cleaning step!!!
This is happening recursively(Every time I launch the update manager). Please can you suggest something?
Logs can be found in the launchpad bug page.
