Warning: My host has no rauc support?

After installing the latest supervisor update 2021.02.05, I see a warning:

21-02-08 15:03:43 WARNING (MainThread) [supervisor.dbus.rauc] Host has no rauc support. OTA updates have been disabled.

This may have been there before…I don’t always check…but I have no idea what RAUC even is and/or what to do about this warning…is something not working that should be working?

Which installation method have you used:

  1. Home Assistant OS
  2. Home Assistant Supervised

If it’s the second one, you can safely ignore the warning message (it refers to a service employed by Supervisor to perform operating system updates which doesn’t apply to you because you manually installed a linux operating system).

If it’s the first one then there’s a problem …
