Hi Anton, Did you install all of the dependencies listed here <https://files.ettus.com/manual/page_build_guide.html#build_dependencies_ubuntu>? The error is a python error in not finding a needed package. It is possible you need to configure PYTHONPATH to point to a UHD folder. Did you specify the FPGA_DIR option to rfnoc_image_builder?

I think I had this problem when I installed UHD to a non-standard location. I did this to my PYTHONPATH variable: export PYTHONPATH=$PYTHONPATH:<UHD_INSTALL_LOCATION>/lib/python3.8/site-packages Where <UHD_INSTALL_LOCATION> is the location where I had UHD installed. Also the Python version (3.8) in that path might be different for you.
