Symptoms

• When checking for system updates in Plesk at Tools & Settings > Update Settings > Available Updates, the operation fails with the error message:

  PLESK_ERROR: Error: Unable to receive update information for the package(s)

• Plesk Installer or system update fails with the error message:

  http://yum.mariadb.org/10.1/centos7-amd64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

Cause

Repository URL for MariaDB 10.1 (end-of-life version) has been changed from http://yum.mariadb.org/10.1 to https://archive.mariadb.org/mariadb-10.1.X by MariaDB vendor.

Resolution

1. Connect to the Plesk server via SSH.

2. Open MariaDB repository file in a text editor. In this example, we are using the vi editor:

   # vi /etc/yum.repos.d/MariaDB.repo

3. Modify baseurl:

   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

4. Save the changes and close the file.

5. Rerun Plesk/system update.
