xiota [1] filed a deletion request for auto-ytdl-git [2]: This package is for the maintainer's personal script. It no longer builds because of missing/broken dependencies. The author/maintainer has also abandoned the project. The git repo (https://github.com/michaelb/auto-ytdl) has the following notice:

I'm not updating this project anymore and some dependencies (kdi3-cli) are now missing in mainstream repos. It may be usable as-is from sources, but there's no guarantee.
