After several weeks testing and check I am near to goal installing Dmrlink in following way:
(snipping commands to install all python library needed...)
"sudo python -m pip install --user dmr_utils"
I found that normal commands to install dmr_utils python library seems not working
you can try to use folowing commands too:
git clone https://github.com/n0mjs710/dmr_utils.git
pip install .
Using mk\sh didn't work for me.
