well now, as of my tests, GitHub Packages for Python is opt-in and not pre-enabled on most repos (correct me if I’m wrong—it’ll help everyone who hits the same issue).

let me show a example:

Language	Where releases usually go	Do they appear in GitHub Packages tab?
JavaScript	npmjs.org	Sometimes (if author also pushes to GitHub npm registry)
Java	Maven Central	Rarely
C#	NuGet.org	Sometimes
Python	PyPI.org	Almost never (GitHub PyPI registry is opt-in & experimental, and as of my searches I haven't seen anyone who have.)

So:

If you want to see …	Look here
Actual Python releases	https://pypi.org/project/
Git tags / GitHub Releases	Repo ➜ “Releases” tab
Source code	Repo ➜ “Code” tab

---

Now for the 404 we’re getting when you do try to upload to GitHub Packages

Command you ran

python -m twine upload \
  --repository-url https://pypi.pkg.github.com/OWNER/REPO \
  dist/* \
  --username GITHUB_USERNAME \
  --password MY_PERSONAL_ACCESS_TOKEN

Error

404 Not Found

Root cause

that endpoint doesn’t exist until the registry is explicitly enabled for the repo
github only exposes the owner-scoped URL (https://pypi.pkg.github.com/OWNER e.g. https://pypi.pkg.github.com/Syqlorix), not the repo-scoped one you tried.

Two ways forward

Option	Steps
Recommended – keep using PyPI (what I and most of projects do)	Just run: twine upload dist/*
Advanced – actually push to GitHub Packages	1. Settings ➜ Packages ➜ enable “Inherit access from source repository” for the PyPI registry. 2. Use the owner-level URL: twine upload --repository-url https://pypi.pkg.github.com/OWNER dist/*

also here's a working sample that maybe can help
