I built a test system with Ubuntu 20.04 and the default version of 
mariadb-server and mythtv v31 was unstable. Since it was a development 
test system, I decided to punt until later. This will have to get fixed 
before I update my v31 production system from 18.04 to 20.04. But I have 
3 years before that is required.
