Thanks for the added information. Your /etc/apparmor.d/local/usr.sbin.cupsd has a lot of extra entries in it. By default it will be empty but it is there for people to use for site-local configuration updates. I see that you currently have: # capability block_suspend,
Which clearly you commented out to avoid the bug. Perhaps you tried a newer cups and made these additions so it would work? Regardless, unless you have a specific reason to do so, I suggest clearing out all the extra entries in /etc/apparmor.d/local/usr.sbin.cupsd for now. Marking "Invalid" since this bug was due to local changes. ** Changed in: cups (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1052098 Title: AppArmor parser error for /etc/apparmor.d/usr.sbin.cupsd Status in “cups” package in Ubuntu: Invalid Bug description: 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.
