If setting the apparmor profile to complain mode still makes it work, then there must be still some kernel messages about denied actions. Your recent debug log (thanks for that) has
[Job 93] Unable to open MFP port device file!: Input/output error But does not say which or where. It's a bit weird, since the current apparmor profile runs unknown backends (like mfp) without any restrictions. Can you please do the following: * Start from a clean boot * Try to print something * Attach /var/log/kern.log here Thank you! -- After update from Feisty to Gutsy RC, print jobs fail: "/usr/lib/cups/backend/mfp failed" https://bugs.launchpad.net/bugs/152537 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
