failure: repodata/repomd.xml from MariaDB106: [Errno 256] No more mirrors to try

Symptoms

When attempting to run yum or dnf, you get an error similar to the following on a CentOS 7 or CloudLinux 7  server:

CONFIG_TEXT: failure: repodata/repomd.xml from MariaDB106: [Errno 256] No more mirrors to try.
https://archive.mariadb.org/mariadb-10.6/yum/centos/7/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found

You will see the following on an AlmaLinux 8 or CloudLinux 8 server:

CONFIG_TEXT: failure: repodata/repomd.xml from MariaDB106: [Errno 256] No more mirrors to try.
https://archive.mariadb.org/mariadb-10.6/yum/centos/8/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found

MultiPHP Manager shows:

When cPanel updates run, errors similar to the following will be logged:

CONFIG_TEXT: [/usr/local/cpanel/scripts/update-packages] Errors during downloading metadata for repository 'MariaDB106':
[/usr/local/cpanel/scripts/update-packages]   - Status code: 404 for https://archive.mariadb.org/mariadb-10.6/yum/centos/8/x86_64/repodata/repomd.xml (IP: 138.201.152.105)
[/usr/local/cpanel/scripts/update-packages] Error: Failed to download metadata for repo 'MariaDB106': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were trie

This would trigger an email notification:

CONFIG_TEXT: Subject: An error occured while updating server software.
cPanel & WHM failed to update server software.
The system failed to update the server software to the latest versions.

“update_packages::UpdateFailed” notifications are currently configured to have an importance of “Low”.

This will also occur when updating MariaDB from a version older then 10.6, to 10.6. Or when elevating a server from CentOS/CloudLinux 7 to AlmaLinux/CloudLinux 8 when using MariaDB 10.6 as the Database server.

Cause

The mariadb-10.6/yum/centos/7/ and mariadb-10.6/yum/centos/8/ folders have been removed from the MariaDB archive. We've filed CPANEL-55968 with our developers to ensure when this Repository file is created it's created with the new correct baseurl.

Resolution

Update the baseurl line of the MariaDB repository to reference "almalinux" instead of "Centos":

An upstream case has been filed with MariaDB:
