    Mlat down and no data since update 1.0.24-4 on my Raspberry, help needed

    Hi folks,
    it seems that during the last update something went wrong.
    Since the last update seems that the feeder goes up, but no MLAT running and no data uploaded.

    Can someone help me to troubleshoot this ?


    the status is ok:

    You probably have dump1090 starting on its own and additionally are using receiverd dvb-t.

    With dvb-t fr24feed wants to start dump1090 itself, it must not be started before.
    Other option is receiver beast-tcp, then you can have dump1090 be started externally.

    If you don't want to configure it yourself, this will correct your configuration:

    I had exactly the same issue since Thursday morning. I was going nowhere fast with FR24 support, so followed wiedehopf's advice and ran his script on GitHub. Problem now solved.
    Regards

    I'm beginning to wonder if the scripted upgrade process has a default config hard-coded or similar. I did a apt install over top, and it tried to tell me there was no configuration file and it would auto run setup at first run. (like a default message)

    Thankfully it did (after a 2nd restart) pickup the my specific config and read the TCP setting and key etc from it. But not before the status screen tried to tell me there was options missing.

    Well, no kidding.

    But just putting it out there, that it seems some specific scenarios are likely once again not being accounted for by fr and overriding.

    I already had them installed/pre run, and it apparently tried to screw with mine.

    I suppose with config dvb-t it might be sufficient to do:

    sudo systemctl disable --now dump1090-mutability
    sudo systemctl restart fr24feed

    This should disable the dump1090 autostart and stop dump1090 if it's running.
    Then fr24feed is restarted and can just start dump1090.
