title: wi-fi disconnected during crouton installation
body: <p>I purchased an Asus c300m with the soul aim of developing my linux skills</p>
  
  <p>I followed the instruction to boot in developer mode and execute the following command to start downloading downloading crouton/ubuntu on it</p>
  
  <pre><code>sudo sh -e ~/Downloads/crouton -t xfce
  </code></pre>
  
  <p>it was going well until my wifi disconnected temporary and i got the following error: </p>
  
  <blockquote>
    <p>E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
    Failed to complete chroot setup
    Unmounting /mtn.stateful_partition/crouton/chroots/precise..</p>
  </blockquote>
  
  <p>Then I tried to run the sudo command again but I got the following:</p>
  
  <blockquote>
    <p>/usr/local/chroots/precise already has stuff in it!<br>
    Either delete it, specify a different name (-n) or specify -u to update it</p>
  </blockquote>
  
  <p>However, I'm not sure how to modify the command so i can resume installation or restart it.</p>
