I think I know what´s causing this: I used some PPA´s which I removed, but I kept using the ppa version of the app The software center keeps the ppa because you still use the ppa version.
After forcing the program back to the lucid version with synaptic, the ppa disappears in the software center after updating the cache. :) -- Software-Center does not remove deactivated ppa's https://bugs.launchpad.net/bugs/574155 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
