Stephen,

I'm glad you posted these comments. I've been wondering about the Ubuntu 
20.04 issue with MariaDB. I'm following the bug report 
(https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1877504) but 
no update lately.

 From my experimenting I believe that if I have to move to Ubuntu 20.04 
before there is a fix, my only choice would be to back everything up 
create a new Ubuntu 20.04 system and NOT install MariDB before I install 
Mythtv v31 and proceed with MySQL 8. I have been able to restore a daily 
backup from MariaDB to a new MySQL system using:

/usr/share/mythtv/mythconverg_restore.pl --drop_database 
--create_database --filename /full path to 
directory/mythconverg-1214-20080626150513.sql.gz
