Hello @burnscm,
thanks to you, we have discovered that the package unipi-kernel-modules v1.54 for Neuron has been incorrectly built. It is now fixed and new OpensourceOS image has been built.
I recommend to download the said image (https://kb.unipi.technology/_media/files:software:os-images:neuron-opensource-os_image-20210105.0.zip) and do apt update && apt install -y evok.
Thank you for understanding and have a nice day,
Martin
