  • Attempt to upgrade Plesk fails with the same error.

Cause

Plesk Management Service is stuck, not started or not available.

Resolution

  1. Connect to the server via RDP.

  2. Restart the Plesk Management Service via Plesk Services Monitor (Plesk icon in the tray menu):

    @Mark Anderson

    Reboot should fix the issue as well, but in this case only Plesk is unavailable, while reboot will cause downtime for all domains on the server. So if only Plesk Management Service is not running, it is better to start only this service.
