Public bug reported: My HP printer suddenly didn't work anymore, and /var/log/syslog reported for udev-configure-printer:
"failed to connect to CUPS server; giving up" I decided to reinstall cups and hplip and got the following error messages: "AppArmor parser error for /etc/apparmor.d/usr.sbin.cupsd in /etc/apparmor.d/usr.sbin.cupsd at line 18: Invalid capability block_suspend." ... and: "start: Job failed to start invoke-rc.d: initscript cups, action "start" failed." ... resulting in errors related to dpkg (dependencies problems). After commenting out the line capability block_suspend, in /etc/apparmor.d/usr.sbin.cupsd, all is well: Reinstalling cups and hplip was successful and my printer works again. ** Affects: apparmor (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1052098 Title: AppArmor parser error for /etc/apparmor.d/usr.sbin.cupsd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1052098/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
