no .git folder

[medyagh]

minikube Make uses git log for getting the commit sha for minikube version,

git log doesn't work in checkouted source code

when I run git log --pretty=oneline
I get this error:

 Not a git repository (or any of the parent directories): .git

If you are running on a self-hosted runner, is your CI checking out your project using git or github REST API ?

[RaiBnod]

I was using self-hosted runner. And it had no .git folder showed me logs as below:

Getting Git version info
  Working directory is '/root/actions-runner/_work/<project>/<project>'
  /usr/bin/git version
  git version 2.17.1
The repository will be downloaded using the GitHub REST API
To create a local Git repository instead, add Git 2.18 or higher to the PATH
Downloading the archive
Writing archive to disk
Extracting the archive

This means, the repository got downloaded using the GitHub REST API, which meant to dowloaded differently.

So for debugging what's going around, I tried on the ubuntu-latest instead of self-hosted and it showed me log something like this:

Getting Git version info
  Working directory is '/home/runner/work/<project>/<project>'
  /usr/bin/git version
  git version 2.28.0
Initializing the repository
  /usr/bin/git init /home/runner/work/<project>/<project>
  Initialized empty Git repository in /home/runner/work/<project>/<project>/.git/
  /usr/bin/git remote add origin https://github.com/<org>/<project>
Disabling automatic garbage collection
  /usr/bin/git config --local gc.auto 0

After comparing those two logs: one is using Git version: 2.17.1, and another one is using Git version: 2.28.0.

Hence, after updating the Git version (>= 2.18) into latest one, the issue got resolved in my case.

I'm using GitHub itself and not a self hosted runner but keep running into the same issue. We use the .git folder during our scripts.

[sohanyadav]

same issue :(

As @RaiBnod already mentioned, upgrading git did the trick for me, too (in my case 2.11.0 -> 2.21.0).

[HebaruSan]

Also seeing lack of .git folder, git reports git version 2.20.1 (believe we are in ubuntu-latest), are there any other known causes?

Why is this version-specific, hasn't git clone created a .git folder standardly for a very long time?

EDIT: Hmm, another version of git is active somehow somewhere? Thanks for the clues about what to investigate...

The repository will be downloaded using the GitHub REST API
To create a local Git repository instead, add Git 2.18 or higher to the PATH

Is this referring to the copy of git installed inside of actions/checkout@v2? How can I upgrade that?

Tried apt-get install git as a step before checkout. Please kill me.

Package git is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'git' has no installation candidate

Is the root cause a TLS thing?

EDIT AGAIN: Apparently what I needed to do was delete this from the workflow file, because then it ... uses something newer? I have no idea:

       container:
           image: ubuntu:latest

I assume that's a restatement of what's already been said above. Included for anyone else who's as clueless as I am.

Self hosted: upgrading git for debian-based distros:

sudo apt-get install -y software-properties-common \
    && sudo apt-get update \
    && sudo add-apt-repository -y ppa:git-core/ppa \
    && sudo apt-get update \
    && sudo apt-get install -y git

Either run it before the checkout action, or, if the runner is a docker container, add as a RUN command

[ktbarrett]

This was also an issue for me (due to use of setuptools_scm on a project I am running in a container) and it took me a good while to find this issue. I think this difference in behavior should be more prevalent in the README.

Any ideas on getting the self-hosted up to a later version? I have the same issue but the older version of git is limiting other features we want. I need at least 2.18 or higher.

2021-04-01: I still see the same problem when running on GitHub itself.

Self hosted: upgrading git for debian-based distros:

sudo apt-get install -y software-properties-common \
    && sudo apt-get update \
    && sudo add-apt-repository -y ppa:git-core/ppa \
    && sudo apt-get update \
    && sudo apt-get install -y git

Either run it before the checkout action, or, if the runner is a docker container, add as a RUN command

Even after running those ^ on a self-hosted docker image I still get the same errors. For some reason I only get a 2.7 version of GIT installed and nothing newer. Cannot seem to get past it.
