MLAT inactive

[Pocokomulama]

Hello.
I am not able to run MLAT for RadarBox in any way I have found.
When I try to run mlat-client manually on my PI I get the following error.

Code: [Select]

mlat-client
Traceback (most recent call last):
  File "/usr/bin/mlat-client", line 108, in <module>
    open(pidfile, 'w').write(pid)
PermissionError: [Errno 13] Permission denied: '/run/mlat-client.pid'
A while ago, I performed the following steps once again.

1. sudo bash -c "$(wget -O - http://apt.rb24.com/inst_rbfeeder.sh)"
2. sudo apt-get install mlat-client -y
3. reboot
4. sudo apt update
