Would you explain what I have to do?

I am just trying to fix some Doxygen -> pdf build fails and am
not a TeX guy.

That repo contains a release per day, does this mean that
tlmgr is only valid for one day, because the next day there
is a new TL release?

 From the answers I already got, I'd conclude that tlmgr
is the wrong tool to manage TeXlive packages, so the
big question is:

What's the proper way / tool to manage TeXlive packages?
