Bug Description

I am running trusty. When I upgraded to cups 1.7.1-5ubuntu3, I got a conffile prompt. I don't believe I've manually modified any cups-related conf files, so I didn't expect a prompt - I expected the package upgrade to handle this for me without a prompt.

Is it possible that you have used a printer setup tool, like system-config-printer or the printer part of the System Settings, to turn on or off sharing of local printers, debug logging, or similar stuff? This also modifies configuration files. The automatic bug reporting system, Apport, has also discovered that your /etc/cups/cupsd.conf file contains modifications.

@Till: I have used a printer setup tool to set up a printer

I assert that setting up a printer should not cause the user to be promoted about conf file changes during an upgrade. This is a normal case, and users should not be required to understand/analyze conf files in order to use a printer.

Did you activate printer sharing some time ago?

@Till: I don't have printer sharing enabled, but I am using some network printers.

See attached screenshot for my printer settings

Perhaps you turned something on one time and later off again. There is an extra "BrowseAddress @LOCAL" in your cupsd.conf, and a "SystemGroup lpadmin". The latter has moved into /etc/cups/cups-files.conf with CUPS 1.6.x.

@Till: It's possible that I turned printer sharing on then off (this machine is new, and I do not recall doing it). I have never touched cuspd.conf by hand on this machine. Any printer setup I did was through the GUI tools. If the setting moved into a different file, we should migrate it as part of the upgrade.

It seems that if you turn on a feature with the cupsctl command or a GUI and turn it off again, that cupsd.conf does not return to its original state again but only to a state whichg fulfills the configuration change request. You could try to report an upstream bug on http://www.cups.org/str.php, but I do not know whether it will get fixed, as the change in cupsd.conf only affects the Debian package system, not the functionality of CUPS.

Note that the printer sharing settings did not move to the new cups-files.conf.

It's a usability issue that doesn't limit the functionality of a core package.
