Unfortunately it only worked for a short time, probably until I made a reboot…
I don’t get any observations anymore…

Can you raise the sample rate, I see some decimation steps in this obs, maybe it isn’t high enough and after decimation there isn’t anything left.

Setting the sample rate to “768e3" in fact fixed it
https://network.satnogs.org/observations/6307151/
Beside this: I do believe the AirSpy HF+ driver is having some problems, probably related to sample rate. Since an update some time ago, I’m seeing strong interference from the repeater outputs below the VHF satellite band… some sort if image rejection filtering no more working. I don’t see this with QubikSDR or SDR#…
But that’s another topic, glad to see my station is running again…

I just ran into this when building a satnogs-client docker image. I had the problem that wget was not installed (and I couldn’t install it because of the broken certificate). So I used curl instead:
curl -vs http://download.opensuse.org/repositories/home:/librespace:/satnogs/Debian_11/Release.key | apt-key --keyring /etc/apt/trusted.gpg add -
