Okay we are getting there, can you provide me the output of
uname -a also can you try sudo bash -c "echo -n /usr/sbin/cupsd >/sys/kernel/security/apparmor/.remove" sudo bash -c "echo -n /usr/lib/cups/backend/cups-pdf >/sys/kernel/security/apparmor/.remove" and then try printing without restarting cups. It looks like the cups package has an apparmor policy hook and is ensuring the cups policy is loaded before it starts the service. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1187970 Title: apparmor prevents custom printer driver from executing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1187970/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
