Comment # 34 on bug 1030829 from Michele Cherici

> All of that is quite unrelated to this bug report though...

Bug title is 'PackageKit should use "zypper dup" instead of "zypper up" on
Tumbleweed'.
I've listed some misbehavior that happens when "zypper dup" is used form
plasma5-pk-update though PackageKit so they are related to this bug report
IMHO.

Anyway up to now nobody else have replied confirming the problems that I've
found in my Tumbleweed installations, so it's possible that there is something
wrong with my setup.
