I alo get the same error. I had some packages that were not required anymore and removed those with apt-get autoremove. But it did not work.
I have attached the log-files suggested and also my original sources.list (which is changed automatically to remove third party repositories during upgrade). ** Attachment added: "log-attachment.tar.gz" http://librarian.launchpad.net/7497122/log-attachment.tar.gz -- Can't calculate the upgrade with unofficial mesa/compiz packages https://bugs.launchpad.net/bugs/58424 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
