Thanks for your bugreport. I looked over the report and it appears that the problem is that during the upgrade calculation lbqapt-runtime keeps libpolkit-qt-1-0 on the machine. But that causes problems later on as kdebase-runtime can not be upgraded.
It seems like this is causes by the following package: Investigating (0) libqapt-runtime [ amd64 ] < 1.1.3-0ubuntu1~maverick1~ppa2 > ( kde ) Broken libqapt-runtime:amd64 Depends on libp Could you please remove the "libqapt-runtime" package that comes from a PPA (or downgrade it and its dependencies) and try the upgrade again? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/798512 Title: Upgrading Kubuntu to version 11.04 error at the second process To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/798512/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
