Symptoms

When trying to run System Updates in Plesk > Tools & Settings > System Updates the following error is shown:

The System Updates tool is already installing updates in automatic mode. Please try later.

The following is shown on attempts to check for updates on command line:

# plesk sbin pum --check
INFO: pum is called with arguments: ['--check']
ERROR: Update operation was locked by another update process (Plesk installer or pum).< ;
ERROR: Exited with returncode 100. exit status 100

There are several Installer processes running:

Cause

Plesk installer processes remain active on a server in the background for 30 minutes. It is expected behavior.

Resolution

Connect to the server via SSH
Run the following command:

# plesk installer stop

Alternatively wait 30 minutes until processes are stopped by Plesk automatically.
