Hi,

Not sure what happened then... The Ubuntu version you are using is quite old so maybe that may have something to do with it... I will need to dig a bit deeper to be sure, but thanks for reporting, it's useful to know if we have other customers with the same issue 🙂

Hi Marjeris,

pip version should be fresh enough, just checked:

pip --version
pip 20.0.2 from /usr/local/lib/python3.7/dist-packages/pip (python 3.7)

This is not a big issue for me because I currently only need the tool only for DFU package generation. In any case, if it does not install out of the box on Ubuntu 10.04 then I guess there are many other customers that may be scratching their heads with this same problem.

Hi Tyler,

My guess is that the problem was related to the pip version, as pip needs to be >=19. When you updated pip which version did you update to?

When you ran it manually afterwards you probably got an older pc-ble-driver-py version, which is not really compatible, but you will not notice until you use BLE DFU.

BR,

Marjeris

UPDATE: I was able to get the nrfutil working on my linux box, but not sure what was the actual issue. Here's the details:

Previously, the setup script failed and threw an error as follows:

error: Could not find suitable distribution for Requirement.parse('pc_ble_driver_py>=0.14.1')

Then I removed the pc_ble_driver_py line from the requirements.txt file and the setup completed, but program would not run. (Because the module could not be loaded at startup)

Finally, I tried installing the module with command:

pip install pc-ble-driver-py

And now I can run the nrfutil just fine. Problem solved, but curious to find out why it wasn't working straight out of the box?

One thing that caught my eye is the naming of the module: in the requirements.txt it is with underscores (pc_ble_driver_py) while the module that I installed manually uses hyphens (pc-ble-driver-py).
