CodeQL fails to get Git version

[ixfd64]

Since about six months ago, CodeQL has been unable to automatically detect the Git version. This causes a warning to be thrown: https://github.com/primesearch/mfaktc/actions/runs/27564026256

Could not determine Git version: Unable to locate executable file: git. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable.

It doesn't actually affect the workflow because the Action falls back to the GitHub API for downloading the repo. However, I'd like to silence the warning so that the workflow output is less cluttered.

We are using v4 for all CodeQL-related Actions.

Hi @ixfd64 👋🏻

Thanks for reporting this. I suspect that the reason you're seeing that happen is because you have container: 'nvcr.io/nvidia/cuda:13.2.1-devel-ubuntu24.04' in your workflow and that container doesn't ship with git. We generally expect git to be available, so a quick way for you to make the output less cluttered might just be to make it available (either with an imagine that has it or by adding a step to install it).
