Pinion: pinion generate throws error: pcbdraw returned non-zero exit status

Hi,

I have Ubuntu 20.04 through WSL on my Windows 10 Pro, pip installed Pinion, installed Kicad 6, installed imagemagick. (in that order, if that is important) Running the template command worked fine (then). When running the generate command, I encountered an issue I cannot resolve myself:

$ pinion generate -b …/ATMega4809_Breakout.kicad_pcb --specification diagram.yaml publish

Is it an issue, that it does not find the libraries? I made the board under Windows, but would like to try out your tool.

What can I do?

Cheers, Marius

edt: When generated the template, I did not apply any changes to that. I don’t know if that is important.
