and a dependency isn’t correctly listed in the pipy package manager

I don’t mean a dependency of yt-dlp, but a dep of Python itself. I suggest you ask around in some Python/Ubuntu forums if you want to to figure out the exact root cause.

If you just want to get yt-dlp working, I have added a workaround. Wait for release or install master branch
