I have seen a lot of people wanting to use LM20 (me included), and they are having problems to get it working...
There are a few issues....
- OK2CQR PPA does not support focal (yet)
- The CQRlog 2.4.0-3 package in the LM20 repository does NOT work due to mysql being automatically installed! You need mariadb
So.... how to install CQRlog that it will work on LM20........
Its quite simple to be honest.... just 2 commands in a shell...
sudo apt install mariadb-common mariadb-server mariadb-client
sudo apt install cqrlog
you will be asked for a password, and you will be asked to press y and enter
After this CQRlog should start normally!
