Hi,
Thanks for your reply. I did purge fr24feed and dump1090-mutability. and then checked the status of dump1090-fa and I still get the same error message. Because of that, I did not continue with step 4. Here is the result:
sudo systemctl status dump1090-fa
β dump1090-fa.service - dump1090 ADS-B receiver (FlightAware customization)
Loaded: loaded (/lib/systemd/system/dump1090-fa.service; enabled; preset: enabled)

Then, I ran: journalctl -xe|grep dump1090 and here is the result:
