Upgrade to 15.3 fine, but root partition full

Finally got it to boot, so the mentioned recommendations worked. Only thing is that the UI looks like hell now, NetworkManager “applet” is gone, some network settings missing, some yast2 settings that require root opens an xterm (xdg-su) window for Password: instead of a modal window etc, but that’s at least more easily fixed.

Thanks a lot for all help!

And a simple zypper up took care of the last issue. Seems like the upgrade did not finish after all.
