UPDATE: This is resolved in AMP release 2.8.0.6
Valve released a broken SteamCMD update for ARM devices that causes the game server to never install/update. Below is a workaround that will be included in the next AMP release.
- Create an instance for a SteamCMD game
- Attempt to update and see that it never downloads the game server
- Go to the Instances tab in ADS
- Click the Folder icon for the instance then click the folder named for that game server (Valheim, ark-sa, etc)
- Rename the
linux64folder tolinuxarm64 - Attempt to update inside the instance again
