Abstract
On Ubuntu Precise, the user isn't allowed to add or remove printers on my machine. Here's how to fix that.
Problem is that the local desktop is no longer allowed to perform administrator actions on the CUPS configuration.
This is in part due to my peculiar PAM settings, but AppArmor is in the way too.
So I set the cups apparmor policy to complain (instead of enforce):
apprentice@pc:~$ sudo aa-complain /etc/apparmor.d/usr.sbin.cupsd
apprentice@pc:~$ sudo ln -s /etc/apparmor.d/usr.sbin.cupsd /etc/apparmor.d/disable/
apprentice@pc:~$ sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.cupsd
There happens to be a little bug in /etc/cups/cupsd.conf, which we remedy by
apprentice@pc:~$ sudo sed -i '/^[[:space:]]*SystemGroup/ s/^/#/' /etc/cups/cupsd.conf
After that, it's generally enough to make yourself a member of the group 'lpadmin'.
