Hello Edouard, I think you left a hardcoded package name in your script, line 29, fix with:
s/python-websockets/$package/ Also you sometimes use $package vs ${package} This kind of thing (maybe converted into scheme what about `guix before-submit') should be a valuable addition to guix, it would help beginners (like me do less mistakes) and comitters could have more confidence in a submission if it has gone through this. Which would in turn enable us to integrate patches quicker. WDYT ? -- Vincent Legoll
