[BUG] Installing a flutter SDK failing

[coups-cs]

Describe the bug

When the fvm cli attempts to install a flutter SDK for the first time there is an Unknown error

ProcessException: Unknown error
     Command: git clone --progress -c advice.detachedHead=false -b stable --reference /Users/user/fvm/cache.git https://github.com/flutter/flutter.git /Users/user/fvm/versions/stable

This is the state of the fvm folder in my user filesystem

If I then attempt to install again it has an issue with the clone repo.

This happens upon installing any version of the Flutter SDK

The issue appears not to be localised to my MacBook, I have found another user is experiencing the same issue.

There's a simple work around which I will post in this thread.

To Reproduce
Steps to reproduce the behavior:

1. Go to terminal.
2. Run fvm install stable or fvm install <Flutter SDK version number>
3. See error

Expected behavior
Flutter SDK version should install correctly into the version folder to be used in your project

Additional context

I have installed the latest version of FVM using brew, however I have experienced the same issue after installing it directly from fvm.app.

I can confirm git is working correctly and I have also updated the git config to allow for larger packet sizes and to accommodate for large repos, but have not seen a change in this error.

Work around (on Mac) is to manually clone the version or stable into your version folder by using the command that failed.

Note: you have to update both the version number/name of destination folder and also the branch flag

git clone --progress -c advice.detachedHead=false -b <branch-name> --reference /Users/<your-user>/fvm/cache.git https://github.com/flutter/flutter.git /Users/<your-user>/fvm/versions/<branch-name>

Once this has installed correctly fvm will pick it up next time you use flutter or try to install the SDK.

bugfix?

[coups-cs]

Installing a new flutter version through FVM is now working for my team. We believe this might have been a github transient issue.
