If a moonraker depending webinterface is installed before moonraker itself, the service restart of nginx will cause an error due to the missing upstreams.conf file which only gets created during the install of moonraker.

possible fix:
decline installation of an interface if moonraker is not installed. the interfaces relais on moonraker, therefore there is no real need to have them installed before having a valid moonraker installation available.
