perl-DBD-MySQL can't install

I Can’t install dnf package perl-DBD-MySQL.
This is probably a problem with the MySQL version.

perl-DBD-MySQL-4.053-1.el9.x86_64 required: libmysqlclient.so.21
but I have libmysqlclient.so.24.0.6…

I tried the “nobest” option but it didn’t find any other candidates to install.

$ sudo dnf install perl-DBD-MySQL

However, I was able to install it last month.
The version combinations used at that time were as follows:

Hello.

Looking at the Requires for the RPM you posted,

Whereas 4.050 leaned toward the MariaDB client side,
from 4.053 onward, it changed to hard dependencies on the Oracle MySQL client (libmysqlclient.so.21).

In the questioner’s environment, the MySQL 8.4 (libmysqlclient.so.24) module is already enabled.
Since mysql-libs 8.0.x, which provides libmysqlclient.so.21, is hidden from dnf due to modular filtering,
the dependencies cannot be satisfied, preventing installation.

Removing libmysqlclient.so.24 carries a high risk of breaking MySQL 8.4 itself and is not a safe workaround.

Therefore, it is recommended to report a bug to AlmaLinux Bugzilla with the following description:
“Unable to install perl-DBD-MySQL-4.053 in a MySQL 8.4 (libmysqlclient.so.24) environment
due to a dependency on libmysqlclient.so.21.”
