The Supervisor needs to have privileged access to the docker runtime on your host to be able to do everything it needs to do.
If you are running an older version of our Home Assistant OS, update it in the Configuration panel.
If this is not our Home Assistant OS, your operating system might be out of date. Try checking for and installing updates, then restarting your system. If this doesn’t work, you may need to re-run our convenience installation script.
