title: how do I pull to a bare repository?
body: <p>I have a "main" bare repository and a "personal" bare repository. I want to update changes form "main" to "personal", so I run:</p>
  
  <pre><code>$ git pull
  fatal: /home/gimenero/applib/git/libexec/git-core/git-pull cannot be used without a working tree.
  </code></pre>
  
  <p>How do I pull the changes pushed to "main"?</p>
