It looks like you already have Docker installed. Umbrel requires a modern version of Docker so this script will update them with the official Docker install script.

If you would like to disable this behaviour you can abort this install and run again with --no-install-docker or --no-install-compose.

You can pass flags to the installer like this:

  curl -L https://umbrel.sh | bash -s -- --no-install-docker --no-install-compose

Sleeping for 30 seconds...

You may press Ctrl+C now to abort the install.

Umbrel has been sucessfully installed!

You can start Umbrel with "newgrp docker && sudo ${UMBREL_INSTALL_PATH}/scripts/start".

You may want to setup a system service that runs "./scripts/start" and "./scripts/stop" at system startup/shutdown.
