That worked for me for zoph, but a new failure occurred in tt-rss.
I'm now trying a transitional mariadb-server-10.5 package which seems to 
work for both these cases. Will do a complete set of piuparts upgrade 
tests for all upgrade paths involving mariadb-server-10.5

Proper error message is good. ;-)
Ignoring the failure not. :-(

While creating the transitional package I came across some 
inconsistencies between Conflicts/Breaks/Replaces. I'm not sure whether 
they are intentional, but I'm doing my tests with the three attached 
patches applied. They didn't make a difference on their own.
