Manually running $ sudo /usr/share/software-center/update-software-center seems to have made the problem go away. Looks like this may have something to do with software-center's xapian cache under /var/cache/software-center/.
BTW I did make a backup of /var/cache/software-center/ before running that command, in case that's useful for debugging. -- 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
