Any hint what’s going wrong?
That did install without problems here.
Hmmm, I think I see the problem

Have to get rid of some stuff, I guess…

Is it possible to shrink swap while running? Guess not… But is it safe to shutdown the machine now with half of the updates installed?
swapoff, repartition, swapon
OK
swapoff -a
then deleting swap in Yast, increasing / and creating a smaller swap followed by
swapon
and the zypper dup succeeded.
