Hello, I solved it by reinstalling the gr-lora module using the below cmake command change:
komro@komro-HP-ProBook-6560b:~/gnuradio/gr-lora/build$ cmake -DCMAKE_INSTALL_PREFIX=/usr ../ #(Also, for ubuntu users!) instead of komro@komro-HP-ProBook-6560b:~/gnuradio/gr-lora/build$ cmake ../ PS: Thank you @Paul!

Hello Paul, The Problem ist hat the suggested gr-lora requires Gnuradio 3.8.2, but I have installed gnuradio 3.8.1 via PPA installation. Do you know if there is any binary installation available for gnuradio 3.8.2 (without having to build it from source)? And, is there no compatibility issues with programs from gnuradio 3.8.1, when using 3.8.2?

Just so you know, there’s a much more up to date, better documented and more thorough implementation of LORA in GNURadio. I wouldn’t mess with the one you’re installing now.
