Hello all,

I have upgraded from Ubuntu 22.04 to Ubuntu 24.04. The upgrade process uninstalls CQRLOG so I have to install it again.
The CQRLOG program can be installed, but when I try to install MariaDB I get always errors related with the package "mysql-server-8.0".
It says that MySQL is frozen and I cannot do any operation. I've tried to uninstall the complete MySQL and I cannot do it.

Command "sudo apt install mariadb-client" returns:
.........

Any idea about how can I unfrozen the MySQL installation?
How can I unlock the situation?
Thank you.
