Due to the fact that MariaDB 10.1, 10.2, and 10.3 reached their end-of-life, the vendor have moved corresponding repositories to archive.

It is strongly recommended to upgrade MariaDB server to the supported one (10.4 - 10.6, 10.11) using the steps from the article How to upgrade MySQL 5.5 to 5.6/5.7 or MariaDB 5.5 to 10.x on Linux?

If the upgrade is not possible for some reasons, apply the following workaround:

Workaround (not recommended)

Warning: Applying the workaround is done with taking the risk of not getting further security updates for MariaDB.

Connect to the Plesk server using SSH.
Open the MariaDB repository file in a text editor. In this example, the vi editor is used:

# vi /etc/yum.repos.d/MariaDB.repo
Modify the option baseurl as described below:
- For MariaDB 10.1:
  
  Note: 10.1.48 is the latest version in MariaDB 10.1 series. Example below is for CentOS 7.
  
  CONFIG_TEXT: [mariadb]
  name = MariaDB
  baseurl = https://archive.mariadb.org/mariadb-10.1.48/yum/centos7-amd64/
  gpgkey = https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
  gpgheck = 1
  enabled = 1
- For MariaDB 10.2:
  
  CONFIG_TEXT: [mariadb]
  name = MariaDB
  baseurl = https://archive.mariadb.org/mariadb-10.2.44/yum/centos7-amd64/
  gpgkey = https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
  gpgheck = 1
  enabled = 1
- For MariaDB 10.3:
  
  CONFIG_TEXT: [mariadb]
  name = MariaDB
  baseurl = https://archive.mariadb.org/mariadb-10.3.39/yum/centos7-amd64/
  gpgkey = https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
  gpgheck = 1
  enabled = 1
Save the changes and close the file.
Rerun Plesk/system update.
