@KarstenV Hello again.
Thanks again for helping to tease out the multi-faceted issues around this last testing update.
Re:
Just wanted to note that we now have 5.0.7-0 out in testing. It should address both the DB format update requirement issue from systems dating back to Leap 15.3, and the failure to remove our legacy Poetry version, both uncovered predominantly in this thread.
See:
A regular command line update of the rockstor rpm should invoke the required DB update and legacy poetry removal. But you system may be in an interim state, so do keep that in mind and report as you go here, just in case.
N.B. you will need to re-install your by-hand removed postgres10 dependencies. That helped to diagnose the problem: but they are a definite required to be installed to perform the db update. The script we added to do this DB update can be run by-hand as root at the command line, and will help to inform you of these requirements. Existing systems will already have these installed as that is what the systemd required before to access the older DB formats.
Hope that helps.
