  INFO: pum is called with arguments: ['--update', '--json', '--', 'MariaDB-client', 'MariaDB-common', 'MariaDB-compat', 'MariaDB-server', 'MariaDB-shared', 'galera-4']

• The server is running with RedHat-based OS.

Cause

MariaDB updated GPG key on February 2023: https://mariadb.org/new-gpg-release-key-rpms/. So they should be updated on RedHat-based OSes (CentOS, Cloudlinux, Amalinux, etc.) manually.

Item for improvement with ID PPPM-13906 was created to handle this situation from the Plesk side.

Resolution

1. Connect to the server via SSH.

2. Execute the command below to update key:

   # rpm --import https://supplychain.mariadb.com/MariaDB-Server-GPG-KEY

3. Re-run Plesk Update.
