Are you using Scalar or VFS for Git?

No - I want to scalar clone, for sparse-checkout ad background maintenance.

If VFS for Git, then what version?

$ gvfs version

** NA **

From some perusing, this problem is rooted in the fact that the latest git was likely compiled on Ubuntu or 22.04 against the newer glibc 2.32-2.34, and therfore won't run on Ubuntu 20.04 which doesn't have those newer glibc libraries by default nor are they installable via apt.

If the git build were to build against the older version, I think it would still be easy to use on Ubuntu 20.04.

If Ubuntu 20.04 is considered an "Older distibution" at this point, it would be helpful to note that up front in the install docs.

This should in fact be updated in the install docs. I believe that Ubuntu 20.04 is approaching end-of-life as far as GitHub Actions is concerned. The ubuntu-latest image is on 22.04 (we use this image), though I can't track down when it switched.

ubuntu-latest, according to the public docs, switched to ubuntu-22.04 in actions/runner-images@9c544f4 (2022-15-15)

Part of actions/runner-images#6399. Not sure when the actual image switch happened.

Thanks for the confirmation, I can open a PR today!

According to https://endoflife.date/ubuntu, Ubuntu 20.04 has only 8 more months of maintenance releases. So yes, I agree that we should upgrade the requirements to 22.04.
