Comment 8 for bug 164821

I am glad that removing the debian line helped. My feeling is that the problem you are currently having is a result of having mixed Debian and Ubuntu packages.

At this point I am going to close this bug. We appreciate the difficulties you are facing, but it would make more sense to raise your question in the support tracker. Please visit https://answers.launchpad.net/ubuntu/+addquestion, and do indicate that you had been using the Debian repository. If it is indeed a problem with the Ubuntu packages, please issue separate bug reports for those packages.
