title: running git remote update all of a sudden returns fatal: unable to fork
body: <p>I ran <code>git remote update</code> on a machine that has been connected and communicating with a repository for a long time. Today when i ran that command it returned the following:</p>
  <pre><code>Fetching origin
  fatal: unable to fork
  error: Could not fetch origin
  </code></pre>
  <p>I have similar issue now with <code>git pull origin master</code> returns <code>fatal: unable to fork</code></p>
  <p>It is a bitbucket repository. I didn't do any forks. What could have caused this?</p>
  <p><strong>UPDATES</strong></p>
  <ul>
  <li>Tried rebooting...same issue after restart</li>
  <li>Checked file permissions were normal</li>
  <li>Checked system resources (plenty of RAM and disk space left)</li>
  <li>Can clone project into a new directory on the same machine but still trying to figure out what made the project in its original directory broken.</li>
  </ul>
  <p>What i ended up doing to get back to work was clone the repo again to a new folder and replacing the <code>.git</code> directory from the original directory with the one from the new clone.</p>
  <p>I'm not sure what went wrong that caused this.</p>
