upgraded linux and now i cant start cqrlog

After upgrading to Linux Mint 20 (And downgrading again to 19.3 with timeshift)
When i run cqrlog i get an error:
Error during connection to database: TMySQL57Connection : Server connect failed.
then the database window opens but no logs available

I ran cqrlog with debug here is the output.

reggy@reggy-asus:~$ cqrlog --debug=1
Fontconfig warning: "/etc/fonts/conf.avail/53-monospace-lcd-filter.conf", line 10: Having multiple values in isn't supported and may not work as expected

upgraded linux and now i cant start cqrlog

Hi!
Open command console and copy this (it is one line) to it and press enter:

/usr/sbin/mysqld --defaults-file=/home/reggy/.config/cqrlog/database/mysql.cnf --datadir=/home/reggy/.config/cqrlog/database/ --datadir=/home/reggy/.config/cqrlog/database/ --socket=/home/reggy/.config/cqrlog/database/sock --port=64000

If I do it with my username and Fedora31 (that has different directtory for mysqld):
[saku@hamtpad ~]$ /usr/libexec/mysqld --defaults-file=/home/saku/.config/cqrlog/database/mysql.cnf --datadir=/home/saku/.config/cqrlog/database/ --datadir=/home/saku/.config/cqrlog/database/ --socket=/home/saku/.config/cqrlog/database/sock --port=64000

I see:

2020-09-02 9:23:43 0 [Note] /usr/libexec/mysqld (mysqld 10.3.22-MariaDB) starting as process 3165 ...

If you see it starting then it is ok. But looking from debug it seems like cqrlog can not start it (not found perhaps?) So many tries, then give up.
Or is there some other error seen from command console. That can not be seen from debug text.

There might be something happened with downgrade.

Hello Regin,

it seems mysql 8 cannot start due to security reasons, which is ubuntu related.

You have to change to mariadb (mysql alternative) which is not too much security regulated, hi.
Please check your databases when you really need mysql 8.

Try the following:
sudo apt install libmariadb3 libmariadb-dev mariadb-common mariadb-server-10.3 mariadb-client-10.3 libcanberra-gtk-module

Mysql 8 is replaced with MariaDB and all "db-problems" are gone :-)
