I am not sure if this is an issue with Python or pygit2, but Pyhton 3.8 and 3.9 are unable to build the pygit2 package, and an error with gcc occurs. This is causing errors on my Travis CI build; here is a link where you can see build logs for my project that depends on pygit2: https://travis-ci.org/dullbananas/shellp

[lazka]

pygit2 requires libgit2 to build which means you need to install the "libgit2-dev" package through apt.

See https://docs.travis-ci.com/user/installing-dependencies/ for how to install packages in your travis-ci setup.

The reason it works with stable Python versions is that pygit2 provides pre-built wheels on pypi for those: https://pypi.org/project/pygit2/#files

Thanks @lazka for the details. I am closing this as third party issue.
