The problem is in python-qt4. Open Synaptic and look at its origin, in my case it was installed locally. I purged n-muench ppa and python-qt4. After that in my source list appeared official ubuntu package: python-qt4: Installed: 4.9.1-2ubuntu1 Candidate: 4.9.1-2ubuntu1 Version table: *** 4.9.1-2ubuntu1 0 500 http://ua.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status
