failure: repodata/repomd.xml from MariaDB103: [Errno 256] No more mirrors to try

Issue

During yum update:

failure: repodata/repomd.xml from MariaDB103: [Errno 256] No more mirrors to try. 

Environment

• MariaDB 10.3

Solution

To resolve this issue, you can try the following steps:

1. First, ensure that the MariaDB repository configuration is correct. The file is usually located at /etc/yum.repos.d/MariaDB.repo or a similar name. Open it and check thebaseurl value set

   baseurl = https://archive.mariadb.org/yum/10.3/rhel/$releasever/$basearch 

2. Temporarily Disable the MariaDB Repository using the following command: (This will update all other packages except those from the MariaDB repository.)

   # yum update --disablerepo=MariaDB103

3. After modifying the repository configuration, clear the yum cache:

   # yum clean all

4. Now try running yum update again.

If you still face issues or if the MariaDB repository URL seems correct, there might be an issue at the MariaDB's end. 

Cause

MariaDB 10.3 reaches its end-of-life and the vendor moved repository to archive. 

Note: the current vendor maintained MariaDB versions are: 10.4, 10.5, 10.6, 10.11
