Sorry I have terrible luck in getting searches to work to find what I wamt. A brief power outage toasted m SD card and had to start from scratch today. My systems hadnt been touch for a very longer time it was working so well. My last backup was from 2017,
Anyways the last fr24 github thing I used from someone no longer exists I would like to put it back on was working great up till yesterday when the power outage toasted the old card.
Thanks for your help in getting me to the solution quciker
I have a short writeup on how to do an alternative install that doesnât include their auto-update and some other stuff i didnât like, see the bottom of this:
Raspbian Lite: ADS B receiver ¡ wiedehopf/adsb-wiki Wiki ¡ GitHub
Also has proper logging via the journal.

Thanks as always for your help⌠been a bih help in the past
I get this error after setup
Job for fr24feed.service failed because the control process exited with error code.
See âsystemctl status fr24feed.serviceâ and âjournalctl -xeâ for details.
Well check the logs as described on that page as well.

thanks for the help just doesnt workâŚoh well
Letâs check something:
file /bin/rm
/bin/rm -f /dev/shm/decoder.txt || echo wat
grep Pre /etc/systemd/system/fr24feed.service
It really should work, what system are you running?
You started from a fresh Rasbpian Buster or from a new piaware sd-card image?
Or did you use your 2017 image?
fresh piaware image seemed fast way to get flight aware back up
And the output for the commands?
You can put the output in a code section:
```
output
```
Like this, then it will display nicer.
pi@piaware:~ $ grep Pre /etc/systemd/system/fr24feed.service
ExecStartPre=/bin/rm -f /dev/shm/decoder.txt
pi@piaware:~ $ file /bin/rm

ExecStartPre=/bin/rm -f /dev/shm/decoder.txt
sorry dont know what code section is
those characters will create one
```
code / output
```
Anyhow ⌠letâs check this:
sudo /bin/rm -f /dev/shm/decoder.txt || echo wat
forgot the sudo.
i get nothing after that last line
pi@piaware:~ $ sudo /bin/rm -f /dev/shm/decoder.txt || echo wat
pi@piaware:~ $
your script appears to install it in a tmp location
Thatâs how it should be.
Not sure why itâs not working then.
sudo systemctl restart fr24feed
sudo journalctl -u fr24feed | tail -n15
Letâs just try again.
And something else to try (maybe this is the issue):
sudo adduser --system --no-create-home fr24
sudo systemctl restart fr24feed
sudo journalctl -u fr24feed | tail -n15
part 1
pi@piaware:~ $ sudo systemctl restart fr24feed
Job for fr24feed.service failed because the control process exited with error code.
See âsystemctl status fr24feed.serviceâ and âjournalctl -xeâ for details.

Ok i think iâve figured out the error, thanks for sticking with me (the guide had a small flaw ⌠forgot the user / group stuff).
Iâve fixed the guide and you can fix your install like this:
sudo wget -O /etc/systemd/system/fr24feed.service https://raw.githubusercontent.com/wiedehopf/adsb-scripts/master/fr24feed.service
sudo systemctl enable fr24feed
sudo adduser --system --no-create-home fr24
sudo systemctl restart fr24feed
sudo journalctl -u fr24feed -ef
That should be it.
The last command is to watch what fr24feed is doing, can be interrupted with Ctrl-C once you donât want to watch it no more.
If there is still an error, let me know.
thanks the user group seems to have fixedâŚby the way should we run ,lat for FR24 which is not in your notes
Please explain, i donât get it.
Oh mlat, i mean ⌠answer the question as you want ⌠so itâs not included in the notes.
