@listepo can you share the version of FVM, I believe this has been fixed in one of the latest versions.

[listepo]

I try install latest version

[listepo]

@leoafarias fvm --version 3.1.3

[listepo]

I found the problem, I didn't have git installed. I think you need to check and display a clear error. cc @leoafarias

@listepo, I'm also encountering this issue. I've verified that I have Git installed. Any insights would be appreciated.

@leoafarias, I'm getting this error despite using FVM v3.1.3, which I believe is the latest version. Any ideas what might be causing this?

[leoafarias]

@Ay0ubCheurfi Can you create a directory and run git clone https://github.com/flutter/flutter.git to see if there is an issue on git?

@listepo Just an update – the issue wasn't reflected correctly in the error message "Exception: Git clone failed". It was my internet connection. Switching networks fixed it.
