Public bug reported:
Binary package hint: cupsys
I did the official release internet upgrade from feisty to hardy. My
network server HP Laserjet has worked fine for years using LPD protocol.
The upgrade took cupsys to 1.3.7-1ubuntu3. I encountered "the usual
perplexing mess" reported by many people, where cups claimed the print
jobs were successful, and the printer status lights flashed, but nothing
ever appeared on paper. A winXP system could still print, but my other
feisty system sometimes suffered the same kind of symptoms (but could
usually be cleared by power-cycling the printer).
Following many other's advice, I found that I could print from hardy if
I power-cycled the printer, rebooted hardy and then run "sudo aa-
complain cupsd". Anything less was unlikely to clear the condition.
Incidentally, when floundering about I had trouble defining and deleting
printers until I discovered the ownership of several files in /etc/cups/
had changed from root.lpadmin to root.lp, so having my user as a member
of the lpadmin group wasn't useful under hardy!
After the aa-complain command, I found this message in /var/log/kern.log
:-
audit(1209558957.602:2): type=1502 operation="inode_permission"
requested_mask="a::" denied_mask="a::" name="/dev/tty" pid=5665
profile="/usr/sbin/cupsd " namespace="default"
The message turns up a lot in searches, but I haven't found a solution
that works for me. I think the aa-logprof command is supposed to find
the audit messages, but it doesn't. I think it should also suggest how
to modify /etc/apparmor.d/usr.sbin.cupsd to resolve the problem, but
perhaps I am too stupid to see how to do it...
I would like to get this problem properly documented and resolved,
because I am sure many other people will upgrade to hardy, especially
from dapper LTS, and will be baffled when they discover their working
printer configurations are hopelessly broken... and they will have never
heard of apparmor.
