Installing RBFEED is not working on Pi

[GER_EDDM]

I tried to install the RBFeeder on my Pi.

I used the instruction https://www.radarbox.com/raspberry-pi/guide

Unfortunately I didn't work. I can not unterstand what's going on wrong.

Can anyone help me?

The configuration files is empty, and when I type the other commands, like

sudo systemctl restart rbfeeder

there is always the answer:
Failed to restart rbfeeder.service: Unit rbfeeder.service failed to load: No such file or directory.

The protocol is attached.

Thank you soo much for your help!

Does your Pi has Raspbnian JESSIE? If yes, that is too old, and there may be compatibilty problem. Better install Raspbian Buster.

If you are not sure, check by this command

lsb_release -sc
