title: What does "urlopen error [Errno -2] Name or service not known" mean?
body: <p>When I execute the command <code>repo upload .</code> I get this error message:
  </p>
  
  <pre class="lang-none prettyprint-override"><code>[FAILED] device/path/to/repository/ branchname          
     (ssh://gerrit.foo.com/: &lt;urlopen error [Errno -2] Name or service not known&gt;)
  </code></pre>
  
  <p>Does anybody know what this means, or how I might get more information?</p>
  
  <p>For what it's worth, I <em>can</em> execute <code>repo sync .</code> with no problems.</p>
