Let me copy-paste my response from two days ago:

If you have spent 8+ hours on this there must be more to tell about it
than a single sentence. What exactly have you done? What are you proud
of you got in there? What did you struggle with? In what way is it
different from what we had before?

I wouldn't know about this directly off-hand, maybe someone else on the
list can chime in? It feels like you're trying to create a scrolling box
inside a scrolling box, which is generally a bad idea.

As said before: focus on getting it working first. We can always
optimise later.

Again, focus on getting the package manager working first, and don't
spend time doing extra things on the side.

The repository is very small, so cleanup wouldn't take long. What were
your reasons to not do this today as you said you would?


When I try to serve the generated repo.json file via "python3 -m
http.server", use "http://localhost:8000/" as URL, and click the Refresh
button, I get this error:
