Describe the bug

After a fresh installation of the 20221108-mark2_base.img image the Raspberry Pi will boot up but cannot start the DBus server. As a result the commands to control fan, LEDs and microphone won't work.

To Reproduce

Steps to reproduce the behavior:

  1. Flash the image to a new SD card
  2. Boot the system
  3. See errors

Expected behavior

DBus server will start as intended.

Additional context

I think the error is related to user permissions since:

Probably related error at boot, the userconfig.service fails as well:

I was able to "fix" the DBus server by removing the --websocket flag from /etc/systemd/system/mark2-hal.service (and reinstalled dbus-hal as root via bash /usr/local/mycroft/mark-2/dbus-hal/install.sh just to make sure).

I'm not sure what the purpose is of the websocket connection as I can't find a server, but at least the tools mark2-fan, led ... work now.

[EDIT] I'm assuming the Websocket server is part of Dinkum's messagebus service but is not installed in the sandbox 🤔
