title: git pull " fatal: Uh oh. Your system reports no Git commands at all."
body: <p>since few days ago I'm working on a new server (moved from old to new with chroot user) 
  from old server I've copied folder .git to a new server.</p>
  
  <p>The problem is that when I type "git pull" then I have error:</p>
  
  <blockquote>
    <p>fatal: Uh oh. Your system reports no Git commands at all.</p>
  </blockquote>
  
  <p>any other commands like git fetch or git merge works fine.</p>
  
  <p>What reason is that I can't use git pull command?</p>
