Warning: the "docker" command appears to already exist on this system.

If you already have Docker installed, this script can cause trouble, which is
why we're displaying this warning and provide the opportunity to cancel the
installation.

If you installed the current Docker package using this script and are using it
again to update Docker, you can safely ignore this message.

You may press Ctrl+C now to abort this script.

• sleep 20

ERROR: Unsupported distribution 'almalinux'

It loops then fails to complete.

The solution is to have Docker already installed and the docker systemd service started on the target server.

AlmaLinux is noted as supported here: https://coolify.io/docs/installation

Steps to Reproduce

1. Load a new installation on AlmaLinux9. This is successful
2. On a second VM, attempt to Validate Server & Install Docker Engine on a supported (according to https://coolify.io/docs/installation) AlmaLinux9 VM
3. The process fails with logs above.
4. Solve by having the Docker engine installed and started on the target VM
