MariaDB update fails in conversion stage

[corneboele]

Hi,

While trying to upgrade CentOS 7 to AlmaLinux 8, I am encountering the following error during the conversion stage:

2024-11-23 07:10:57.188 DEBUG    PID: 1193 leapp.workflow.RPMUpgrade.dnf_upgrade_transaction:  Trying to start service mariadb... done
2024-11-23 07:10:57.209 DEBUG    PID: 1193 leapp.workflow.RPMUpgrade.dnf_upgrade_transaction:  Trying to establish test connection... /usr/bin/mysql: Deprecated program name. It will be removed in a future release, use '/usr/bin/mariadb' instead
2024-11-23 07:10:57.225 DEBUG    PID: 1193 leapp.workflow.RPMUpgrade.dnf_upgrade_transaction: ERROR 2002 (HY000): Can't connect to local server through socket '/var/lib/mysql/mysql.sock' (2)

I think there is nothing special about my MariaDB installation. Recently I upgraded it using the Plesk UI.

Attached you will find the feedback file.

Any idea what I can do to resolve or to check?

Thank you for your support!

Hi @corneboele,
Could you try enabling the MariaDB service manually and then provide the journal logs afterward?

I wasn't sure what went wrong earlier, as I had tried about four times before and encountered the same error each time. To get the journal logs I tried another time. This time, however, everything worked and the full conversion succeeded. I followed the same steps as before.

The only difference this time was that it didn't attempt to upgrade from MariaDB 10.11 to 11.5, and it stayed on version 10.11. I think that's fine for now.

So, case closed. Thanks for your support!
