title: Why Gerrit is unable to create branch by itself?
body: <p>Following <a href="https://stackoverflow.com/a/10461674/1469208">this answer</a> and <a href="https://stackoverflow.com/q/20583800/1469208">my own question</a>, I have a simple (hope so) question.</p>
  
  <p>If I'm pushing a particular branch, with all required refs properly set:</p>
  
  <pre><code>git checkout 82-blah-blah
  git push origin HEAD:refs/for/82-blah-blah
  </code></pre>
  
  <p>Why do I always get:</p>
  
  <pre><code>! [remote rejected] HEAD -&gt; refs/for/82-blah-blah (branch 82-blah-blah not found)
  </code></pre>
  
  <p>and I always have to go to Gerrit's UI and create that branch manually?</p>
  
  <p>Isn't that an obvious step, that Gerrit could simply automate? Or am I missing something? </p>
