When you upgrade using the `zypper` CPI tool and there is an ambiguous
packaging situation, a prompt is presented to the user requesting that a
decision be made regarding how to proceed.

However the Zypp PackageKit plugin has no facility to do this, and also does
not choose a default answer. As a result, whenever you update your system using
GNOME Software, KDE Discover, plasma-pk-updates, or another PackageKit-using
GUI tool and such a situation crops up, the update process just fails and
cannot be completed. The update must be performed using the CLI.

This is not very user friendly. If I installed openSUSE on my mother's
computer, I would get a panicked phone call every time this happened and have
to perform the update manually.

Other PackageKit plugins (e.g. aptcc) manage to choose a safe default answer
instead of prompting for user input in these kinds of circumstances. The Zypp
plugin could and should as well.
