thanks to Atri & Neil....

What threw me is that not using the downgrade-nixing switch zypper asks me for the DVD 'openSUSE-20200214-0' which in this case is unreadable (not the first time that this happens for some reason). So I removed it as a repo source with Yast and all went well. TW being a live or hot repo structure I wonder why the DVD was in the repo list at all, technically it becomes obsolete minutes after installation. Even if available the on-line repos would be prioritised I think. So the issue is resolved, remains the question of why the DVD's become unreadable, it's THE reason I had looked into trying to stop downgrades in the first place?

It was there because you failed to remove it after installation.

the only remove prompt I remember was to pull the DVD from the drive :-)

There is no prompt. You are the administrator of a Linux system and you should know what to do >:-) If you think it should happen automatically, open a Bugzilla. But I do not see how that removal could happen automatically. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
