after upgrade printer properties not recognized (paper, duplex etc)

[Darko Veberic]

after an upgrade from ubuntu 15.04 to 15.10 the print dialogs (eg in okular, firefox etc) do not display any printer properties and do not allow to change anything. for example, default paper setting for our main printer is now in okular "Letter" while it's clearly an "A4" printer. in okular and firefox one cannot change the duplex options anymore.

in short: while remote printers are still recognized and listed, it seems their settings are not.

while my clients are version 2.1.0, our institute cups server runs version 1.5.3 and i don't see any easy way we can force them to upgrade it.

i tried to force the lower version by stopping both cups services (cups and cups-browsed) and creating an /etc/cups/client.conf with ServerName x.y.z/version=1.1 but it seems this is not supported anymore. lpstat does not see any printers but the "add /version=1.1" message is still issued, although obviously not supported. are these inconsistencies any indication of a possible bug?

The apparmor denials have since been fixed. Removing the apparmor tag.
