[SRU Oneiric] gnome-shell users get GNOME3's new printer setup tool by default and this tool needs cups-pk-helper

[Till Kamppeter]

gnome-shell users do not get system-config-printer as default printer setup tool but the new tool which comes with gnome-control-center (System Settings) of GNOME 3. This tool does not use CUPS' own authentication mechanisms ("lpadmin" group) for administrative tasks but PolicyKit through cups-pk-helper. As cups-pk-helper is not installed by default, most users have an unusable printer tool (without Unlock button).

The proposed SRU for Oneiric adds a dependency on cups-pk-helper to the gnome-shell, so that at least all gnome-shell users will have cups-pk-helper installed. We do not add this dependency to gnome-control-center as cups-pk-helper is in Universe and gnome-control-center in Main, and most users of gnome-control-center have a Unity desktop which is used with system-config-printer and so they do not need cups-pk-helper.

This is an interim solution until the new GNOME printer tool will be enhanced with functionality of system-config-printer and then made the default for everyone.

Uploaded the fixed gnome-shell package to oneiric-proposed. Please test it as soon as it gets approved. This will be announced with a comment in this bug report. A debdiff of the changes is attached.

Till, why don't we push this update along with the gshell 3.2.1 update? I
was planning on packaging it tomorrow if no one else had gotten to it.

[Till Kamppeter (till-kamppeter)]

Jeremy, feel free to join the two SRUs to one. Rodrigo Moya asked me for uploading as SRU for the cups-pk-helper dependency.

That's fine. Just upload a followup, then I'll reject Till's upload
and take your's instead.

[Martin Pitt (pitti)]

gnome-shell already recommends cups-pk-helper, so it should already work in oneiric final. What went wrong there? Did you install with --no-install-recommends or something similar?

I reject Till's upload because that now has a recommend _and_ a depends, and Jeremy will do a 3.2.1 upload.

[Till Kamppeter (till-kamppeter)]

I have a machine on which I did the Oneiric development going through all the Oneiric development from stable Natty with daily updates during the cycle. Now it has the current Oneiric. One day there was an incompatibility of system-config-printer with cups-pk-helper (this is fixed in current Oneiric). So I removed cups-pk-helper manually. Later on I continued doing updates and this seems not to have re-installed cups-pk-helper.

Now my doubt is whether Recommends is strong enough or whether Depends would be better here. A manual (or conflict-induced) deinstallation of cups-pk-helper would break the printer tool.

[Martin Pitt (pitti)]

Thanks for the explanation. I'm ok with adding a strong depends, but it shouldn't affect a lot of people, so lowering severity.

[Martin Pitt (pitti)]

Hello Till, or anyone else affected,

Accepted gnome-shell into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Then new gnome-shell has indeed a hard dependency on cups-pk-helper, so the reported problem cannot occur any more.
