'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?

使用所示的 Configuration.BuildFrom 和 Push 程式碼，在 macOS 15.4.1 上重現 push。先從 Configuration.cs:75 開始，接著追蹤 Repository.cs:220、Branch.cs:181 和 Network.cs:327，以判斷為什麼需要 ProgramData 設定。完成的標準是 repository 可以在沒有缺少設定例外的情況下 push，並且為回報的設定路徑提供涵蓋。
