Hi,

you add a PPA to your repositories. Don't you remember for what purpose
you add this PPA?

If you shouldn't know what a PPA is, consider to google it.

The package is provided by the official Ubuntu repository, too. It's
available by main. It's just a different version, see

https://packages.ubuntu.com/eoan/libosmesa6

Usually upstream for Ubuntu is Debian, so you could take a look at the
Debian tracker, see

https://tracker.debian.org/pkg/mesa

The link to "real" upstream is provided by the Ubuntu package search as
well as by the Debian tracker. If you want to know for what it's good
for, what is using it, take a look at the homepage's introduction:

https://mesa3d.org/intro.html

Upstream not necessarily hosts sources at github, gitlab, sourceforge
and Co., let alone that upstream not necessarily provides a
package"-file".

Hth,
Ralf
