Public bug reported: For some reason /usr/sbin/cupsd tries to access /var/cache/samba/gencache.tdb. I have a printer setup via samba so that may be the reason.
The apparmor profile for cupsd does not allow this. I get this error in the logs: kernel: [284527.967015] type=1400 audit(1411040510.770:103): apparmor="DENIED" operation="open" profile="/usr/sbin/cupsd" name="/var/cache/samba/gencache.tdb" pid=1722 comm="smb" requested_mask="r" denied_mask="r" fsuid=7 ouid=0 A listing of the apparmor profile (/etc/apparmor.d/usr.sbin.cupsd) is here: http://pastebin.ubuntu.com/8372024/ The file /etc/apparmor.d/usr.sbin.cupsd belongs to the cups-daemon package The system silently fails to print from GUI. The fanny part is that I printed something successfully the day I set the printer up (yesterday).
