title: Cannot start docker on lubuntu - "cannot start container: exec format error"
body: <p>I ran <code>sudo apt-get install docker.io</code> in my lubuntu 14.10, but it says <code>cannot start container</code> when I run this: </p>
  
  <pre><code>sudo docker run ubuntu echo "Hello World"
  
  exec format error2015/03/16 16:31:16 Error response from daemon: Cannot start container ad265ac9c2635f42e4244472d181a2121ecba4d855fa33c10599d91aa932d2cd: exec format error
  </code></pre>
  
  <p>Can not find out the answer, guest it maybe related with the lubuntu.</p>
  
  <p>The container is created, but why do I only got the "exec format error"</p>
  
  <pre><code>sudo docker ps -a
