This is a current known bug. I expect they will fix it next patch.

Fix: AMP fails to start on boot (mistyped ExecStart)

Cause: The ExecStart line in the AMP systemd service is missing the boot delay argument, causing a syntax error that prevents the instance manager service from starting.

Fix:

  1. Open the service file:
   sudo nano /etc/systemd/system/ampinstmgr.service
  1. Find this line:
   ExecStart=/opt/cubecoders/amp/ampinstmgr startboot true
  1. Change it to:
   ExecStart=/opt/cubecoders/amp/ampinstmgr startboot 0 true
  1. Save and exit.
  2. Reload systemd and start the service:
   sudo systemctl daemon-reload
   sudo systemctl start ampinstmgr.service

Why this works: The startboot command expects a delay value (in milliseconds) as an argument. Without it, the line is malformed and systemd fails to parse it. Adding 0 sets the delay to none, which resolves the syntax error and allows auto-boot to run correctly.

Note! I saw in discord that if you make this change, Iceofwraith indicated the next update will break! If you do this make sure to revert before you run the next patch!

Ok - thanks for that hint.
