I supopse there are lot of HAM operators who upgraded from Ubuntu 18.04 to 20.4 do some clean install on ham software they use, including CQR Log.
I faced problems with MySql database in reports saying it could not initialise database or similar.
Looks like instead of MySql , CQR Log use Mariana DB .
So I tried first to install mariana db:
sudo apt install mariadb-server-10.3
and then to install CQLog.
Looks like it works. Mariana db also uninstall mysql from your computer so it should also work if you have previously installed cqrlog and had the problem with database.
