'LibGit2Sharp.NotFoundException: the ProgramData file 'config' doesn't exist' when pushing on MacOS

Hello,

I am facing this issue on MacOS 15.4.1 Sequoia, Apple M2.

I am trying to push some changes I made, to the remote location but I get the following exception thrown when pushing (cloning and committing the changes obviously worked fine).

There is a .gitconfig in my user home directory with the according user.name & user.email section key value pairs.
Additionally I update the local /.git/config file with these information and manually checked that the file is actually updated.

Is this a bug? And if so, is it related to https://github.com/libgit2/libgit2sharp/issues/2046?

But the more pressing question is, how can I workaround this issue?

Here is the stack trace, saying the config file cannot be found in the program data (which obviously is a windows related naming):

Here is my code to update the local config file:

private static Configuration BuildConfuration(string repositoryLocation, string username, string email) Configuration.BuildFrom(repositoryLocation + "/.git/config", userHomeFolder() + "/.gitconfig");
        configuration.Add("user.name", username);
        configuration.Add("user.email", email, ConfigurationLevel.Local);

Here is the code that produces the exception:

private static void CommitAndPushVersionChanges(string repository, string branch, string email, string username, string token)
{
        using var repo = new Repository(repository);

        // Stage the file
        repo.Index.Add("a.txt");
        repo.Index.Write();

        var configuration = BuildConfiguration(repository, username, email);
        var author = configuration.BuildSignature(DateTimeOffset.Now);

        // Commit & Push to the repository
        repo.Commit($"Commit Message", author, author);
        
        var options = new PushOptions
        {
            CredentialsProvider = (_, _, _) =>
                new UsernamePasswordCredentials
                {
                    Username = "x-token-auth",
                    Password = token
                }
        };

        // EXCEPTION IS THROWN FOR THIS CALL
        repo.Network.Push(repo.Branches[branch], options);
}

Can anybody help?

Tái hiện thao tác push trên macOS 15.4.1 bằng mã Configuration.BuildFrom và Push đã cho. Bắt đầu với Configuration.cs:75, sau đó theo dõi Repository.cs:220, Branch.cs:181 và Network.cs:327 để xác định tại sao cấu hình ProgramData là bắt buộc. Hoàn tất có nghĩa là repository có thể push mà không gặp ngoại lệ thiếu cấu hình, với coverage cho đường dẫn cấu hình được báo cáo.
