title: Unable to resolve reference on git fetch origin
body: <p>When I try to update my local code base with <code>git fetch origin</code> I get this error. Do I need to delete local branch and try again?</p>
  
  <pre><code>error: unable to resolve reference refs/remotes/origin/CICO-20404: Success
  From github.com:**********/***
   ! [new branch]      CICO-20404 -&gt; origin/CICO-20404  (unable to update local ref)
  </code></pre>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>I tried <code>git gc --prune=now</code> (suggested by colleague) and now it at-least finish the fetch before showing the error.</p>
  
  <p>Can anyone explain what the heck is going on.</p>
