Comment # 1 on bug 934553 from Wolfgang Bauer

The issue with the updater hanging when a license agreement is necessary has
already been reported as bug#908730 .

I never saw this on 13.1 though (which I don't use any more).
Did you update PackageKit to a newer version from some additional repo there
maybe?

And what exactly is this "conflict" you mention?
Apper/PackageKit do not allow to resolve conflicts manually. They just fail if
there is a conflict.
Or are you using YaST in this case?
