title: unable to spawn git no such file or directory on a specific fork on github
body: <p>The problem is with this fork/repo :
  <a href="https://github.com/RubenWillems/CCNet" rel="nofollow">https://github.com/RubenWillems/CCNet</a></p>
  
  <p>I can get other forks on the same laptop, but not this one.
  trying with ssh gives the same problem.</p>
  
  <p>I'm suspecting a security setup issue with the fork, but I have no idea.</p>
  
  <p>Any idea on how to (start) tackling this, I am quite new to git.</p>
