FYI
There is also in install script at
?
It is for Ubuntu but I guess that it would go also with Mint (not tested).
It does the job from beginning including MariaDB, no need to install any package versions of Cqrlog first.
Script installs first all dependencies and after that the latest official Cqrlog (the tgz file from cqrlog.com/download).
Then it offers direct update to CqrlogAlpha.
