AttributeError:module'lora' has no attribute 'lora_receiver'

[nosferatu2]

I am following the instructions for viewing LoRa, but am getting the error "AttributeError:Module 'lora' has no attribute 'lora_receiver' and am unsure how to remedy. Any help would be appreciated =-)

When installing gr-lora - after the cmake command within the build folder I get the following error:

CMake Error at CMakeLists.txt:87 (find_package):
Could not find a configuration file for package "Gnuradio" that is compatible with requested version "3.9".

The following configuration files were considered but not accepted:

/usr/lib/x86_64-linux-gnu/cmake/gnuradio/GnuradioConfig.cmake, version 3.8.1.0
/lib/x86_64-linux-gnu/cmake/gnuradio/GnuradioConfig.cmake, version 3.8.1.0

-- Configuring incomplete, errors occurred!

Note this:
Could not find a configuration file for package "Gnuradio" that is compatible with requested version "3.9".

Looks like the version of gr-lora you are compiling needs Gnuradio version 3.9
Default version installed by apt-get on Ubuntu 20.04 is 3.8
