Package: cups-daemon
Version: 2.2.6-2
Severity: normal
File: /etc/cups/cups-files.conf

Dear Maintainer,
per the man page root should be in cups-files.conf SystemGroup.
JobPrivateAccess requires @SYSTEM or @OWNER but root in not in any of
those. Thus root cannot job-edit (cancel jobs)
This forbid cups-pk-helper from cancelling jobs as it run as root.

A workaround is adding "root" to "SystemGroup" (which includes
only lpadmin on debian).
We might want to include more following man page which tells:
 The default contains "admin", "lpadmin", "root", "sys", and/or "system".


This affect cups >= 1.5 since the introduction of "private job values".

One such consumer of cups-pk-helper is gnome-control-center printer
panel.


Best regards,
Alban
