Cause

Bug recognized PPPM-14817 that is planned to be fixed in one of the future Plesk updates.

Resolution

When a fix is released, it will show up on Change Logs for Plesk Obsidian.

Until a fix is not release, please use the the following workaround:

• Install maria DB 11.4 before install Plesk.
• Use the following commands:

  # cd /usr/bin/

  # ln -s mariadb-dump mysqldump

  # ln -s mariadb mysq

• Then re-run Plesk installer.
