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 doesn’t include their auto-update and some other stuff i didn’t like, see the bottom of this:  
[Raspbian Lite: ADS B receiver · wiedehopf/adsb-wiki Wiki · GitHub](https://github.com/wiedehopf/adsb-wiki/wiki/Raspbian-Lite:-ADS-B-receiver)

Also has proper logging via the journal.

Let’s check something:

```auto
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?

And the output for the commands?  
You can put the output in a code section:  
```  
output  
```

Like this, then it will display nicer.

That’s how it should be.  
Not sure why it’s not working then.

```auto
sudo systemctl restart fr24feed
sudo journalctl -u fr24feed | tail -n15

```

Let’s just try again.

And something else to try (maybe this is the issue):

```auto
sudo adduser --system --no-create-home fr24
sudo systemctl restart fr24feed
sudo journalctl -u fr24feed | tail -n15

```

Ok i think i’ve figured out the error, thanks for sticking with me (the guide had a small flaw … forgot the user / group stuff).  
I’ve fixed the guide and you can fix your install like this:

```auto
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 don’t want to watch it no more.  
If there is still an error, let me know.
