[error] table plugin: Failed to open file "/sys/class/thermal/thermal_zone0/temp": No such file or directory.

Hi @mikenye

These containers have been so helpful for me getting started with ADS-B, thank you for creating them and putting together the guide!

I've got the readsb-protobuf container up and running, and it's successfully feeding to other containers. I am, however, getting some errors, though they don't seem to cause it to break that I can tell.

Is the thermal_zone0 something specific to Raspberry Pi? I am running this on an x86 server running Debian. Or maybe this is a device that I need to pass through to the container?

Attaching my relevant docker-compose here. You should likely be able to ignore the references to traefik, that's just my reverse proxy to publish these services on my dns. The adsb network is shared by all of your containers, because I have a lot of containers running and keep them on separated networks when possible.

networks:
  adsb:
    driver: bridge
  traefik_proxy:
    external:

Looks like this can be solved with the same "fake thermal directory" solution as found in sdr-enthusiasts/docker-radarbox#16 (comment).

More details on the solution also found in the documentation at https://mikenye.gitbook.io/ads-b/feeder-containers/feeding-radarbox#segfault-fix

Closing issue

[SingingDwarf]

The segfault fix description that was in the documentation relating to radarbox has now been removed, as it is no longer needed for the open source rbfeeder (see sdr-enthusiasts/gitbook-adsb-guide#50)

Details of the fix can still be viewed here - https://github.com/sdr-enthusiasts/gitbook-adsb-guide/pull/50/files#diff-f7156d98a465e6f1fe85dbdab860932fbfa8f95c44d64e657b8e4a2ed0d1d5ff

@SingingDwarf the open source rbfeeder is not supported to feed to RadarBox. Don't use it. Yes I know it sounds stupid, but that's the way it is.
