Hi, seems that I had a similar problem with AppArmor. Errors related with this app were thrown by trying to start cups (see log file). I fixed the problem by removing AppArmor.
sudo apt-get remove AppArmor Hope it helps. ** Attachment added: "log" https://bugs.launchpad.net/ubuntu/+source/cups/+bug/908594/+attachment/3033555/+files/log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/908594 Title: start: Job failed to start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/908594/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
