Plesk Update Manager will not perform any update operations until Plesk installation is fixed

    We have the same problem, however, do not want to go through the full install process (again), as that will mean downtime, possible configuration loss, etc.

    What other solution can you provide?

    Thank you

    Actually, just executed this command and the problem is fixed now: plesk repair installation
