Cause

The perl-DBD-MySQL package updated, which requires mysql-common to also be installed on the same system. This conflicts with servers that are running MariaDB. This is being tracked with case CPANEL-50477.

Resolution

Remove the perl-DBD-MySQL package and install perl-DBD-MariaDB:

# dnf remove perl-DBD-MySQL
# dnf install perl-DBD-MariaDB
