Problems with pynrfjprog in docker container ubuntu

[Dan_e]

I have a problem with pynrfjprog in my docker container. The code works like a charm in windows and linux but when I execute it through my docker container in ubuntu I get this error:

/usr/local/lib/python3.10/dist-packages/pynrfjprog/__init__.py:24: in set_worker_executable
    lib_path.chmod(expected | mode)
/usr/lib/python3.10/pathlib.py:1191: in chmod
    self._accessor.chmod(self, mode, follow_symlinks=follow_symlinks)
E   PermissionError: [Errno 1] Operation not permitted: '/usr/local/lib/python3.10/dist-packages/pynrfjprog/lib_x64/jlinkarm_nrf_worker.exe'

Why is it trying to run the exefile?! Im running ubuntu in my container and ubuntu aswell on my machine. Ive tried different versions of pynrfjprog without success. All dependencies are installed correctly and the file jlinkarm_nrf_worker_linux is in that folder with the exe file but I cant get it to choose it. Ive tried the same thing on a ubuntu vmware and the same error.

Please help, Im going semi crazy

Hi,

I am not able to explain this. Can you share your docker container along with a description on how to reproduce it?

I have tried to remove everything obsolete.

Here is from my docker container:

FROM ubuntu:latest

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update \
 && apt-get install -y \
    build-essential \
    curl \
    git \
    iputils-ping \
    libglib2.0-dev \
    libncurses5 \
    python3-pip \
    wget \
 && rm -fr /var/lib/apt/lists/*

RUN apt-get update && apt-get install -y

RUN apt-get update && apt-get install -y wget udev

RUN pip3 install --upgrade pip

COPY requirements.txt requirements.txt

RUN pip3 install -r requirements.txt

RUN useradd --groups dialout -ms /bin/bash tester

USER tester
ENV HOME /home/tester
ENV PYTHONPATH=rig/
WORKDIR /home/tester


    and this in requirements.txt:
    wheel
    docopt
    pytest
    pytest-dependency
    pytest-ordering
    pytest-cov
    pynrfjprog
    
 My py file contains a single line now: import pynrfjprog
Then I run the docker container with pytest and I get this error

Hi,

I have forwarded this to the responsible team that is working for a fix. In the mean time, you should be able to resolve the issue by simply removing jlinkarm_nrf_worker.exe as it is anyway not used (it is for Windows only).

That actually works! First I just tried renaming the file and that didnt work but deleting it works. Thanks!
