Python GIT CHeckout failed due to: exit code(1)

Question

i have an git repo in gitlab. I tried to checkout the master branch with the following lines.

repo = git.Repo(os.path.dirname(__file__), search_parent_directories=True) repo.git.checkout("master") ref_repo_root = os.path.join(WORKING_DIRECTORY, 'ref_decoders')

But i got the following error.

E git.exc.GitCommandError: Cmd('git') failed due to: exit code(1) E cmdline: git checkout master E stderr: 'error: pathspec 'master' did not match any file(s) known to git.'

What i know repo.git.checkout("HEAD~1") works fine. Where is my issue?

Is there in fact a branch named master? That isn't exactly guaranteed any more - for political reasons, some hosting services arrange things (or give you setup steps to arrange things) to name the primary branch something else. — Karl Knechtel

To be clear, are you using this package to interface with git? Or something else? — Karl Knechtel

What branches does the repository have? Run git branch -a. — ElpieKay

The default branch in gitlab since v14.0 is main and not master. Read here for more info: https://about.gitlab.com/blog/2021/03/10/new-git-default-branch-name/

Hi, thanks for this hint. But i got the same issue. E git.exc.GitCommandError: Cmd('git') failed due to: exit code(1) E cmdline: git checkout main E stderr: 'error: pathspec 'main' did not match any file(s) known to git.'

Does the master/main branch exist at all?

Hi Gabip, the master does exist.

You mentioned that repo.git.checkout("HEAD~1") works. What branch does git think you're on currently (what does it say in git status)?
