Made a script that installs official version 2.5.2 of Cqrlog to Ubuntu 22.04 without using installation packet that wrongly installs Mysql instead of needed MariaDB.

Script installs first needed dependencies (as packets) and then installs Cqrlog from cqrlog.com/Download /cqrlog_2.5.2_amd64.tar.gz
By installed this way system updates can not roll over this install as it does not show up in installed packets list.

Script can also update installed official version right away to latest CqrlogAlpha (unofficial version) if user wants so.

There is no guarantee but I did test it quite many times to plain Ubuntu 22.04 running in Oracle virtual machine (fastest way to restore plain Ubuntu for repeating test)
