It took me some hours to migrate my vmware 42.3 machine to Vbox. Like do something, then wait for completion while doing something else while the VM chugs along, then forgetting. I struggled and failed to get the guest tools installed. Thus I can not copy-paste text. Finally, I took a snapshot and proceeded to upgrade. I forgot to add your modified repo. It did not crash, but there was a curious message somewhere along saying, when some lvm thing crashed, that due to a previous systemd crash coredumps were disabled. But I could not find clues to that previous systemd crash. I will now try to extract that data. Huh, the upgrade changed the session login manager, and this changed default session from xfce to plasma. Possibly another bug.

I have stored the logs safely (yast save logs and some others), in case you want them. I will try, this afternoon, to apply (undo?) the snapshot and redo dup with the test repo added. Even if it runs slow, I don't have to tend to it much :-)
