Segmentation Fault

SatNOGS Software

Recently, I moved to a new home and restarted the satnogs-client on the same device (=Raspberry Pi and RTL-SDR).
It was working fine before, while the signal was a little weak. However, it doesn’t work now.
The log for an observation is shown below.

Following the troubleshooting page (Troubleshooting - SatNOGS Wiki), I have confirmed that rtl_test is working. But satnogs_afsk1200_ax25.py returns “Segmentation fault”.

I have no idea why it turns to fail now and what to do, so I would appreciate it if someone could give me some advice.

This problem was solved by myself.

I checked the behaviour of satnogs_afsk1200_ax25.py line by line and found that from gnuradio import analog caused the segmentation fault.

So,

  1. I uninstalled the libgnuradio-analog3.8.2 and other related packages.
  2. I reinstalled the libgnuradio-analog3.8.2.
  3. I set up the satnogs-client using ansible.
    Then, satnogs_afsk1200_ax25.py works!

Thanks for all.
