Title: CUPS not allowed to mknod to /var/log by apparmor Status in cups package in Ubuntu: Invalid Bug description: I have a two-machine network, both running 14.04.1 but mostly updated. CUPS version is 1.7.2-0ubuntu1 Machine A - has printer attached Machine B - printing to A doesn't work via CUPS I cannot print to the CUPS-managed printer attached to A from B, except with a few apps which see the printer directly via avahi (e.g. Evince).

For example https://bugs.launchpad.net/ubuntu/+source/cups/+bug/810687 didn't allow CUPS to start, but CUPS does start, just doesn't work. Also that bug was reportedly fixed in CUPS 1.4.7.
