I'm not sure whether the problem has anything to do with computer-janitor (which, by the way, I can't really recommend...) or with an incomplete update and some problems with your packages. In a terminal, could you try: sudo apt-get clean sudo apt-get update sudo apt-get upgrade
And if you do get any warnings about conflicts, unmet dependencies etc.: sudo apt-get -f install -- Computer Janitor gives misleading error message "close other package managers" when none are running https://bugs.launchpad.net/bugs/657198 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
