ANYONE WILLING TO HELP?




Hi!
You have Mysql in your system by your message: "(mysqld 8.0.43-0ubuntu0.24.04.2) starting as process 7714"
You must install MariaDB that overrides Mysql.
You need packages: libmariadb-dev-compat mariadb-client mariadb-server mariadb-common
After that If you want a clean restart (note: all logs deleted if exist!) remove hidden folder ~/.config/cqrlog before starting Cqrlog again.
