title: Error response from daemon: No such image: ubuntu (tag: latest) right after after pulling from docker hub
body: <p>I had pulled the image <code>ubuntu</code> from the docker hub after a search using - 
  <code>sudo docker search ubuntu</code> and pulled the image using <code>sudo docker pull ubuntu</code>. The command - <code>sudo docker images</code> were listing around 5 images related to ubuntu with different tags. The curious part is, I was not able to run the image - <code>ubuntu</code> with any of the tags available even with the default - <code>latest</code> tag..! The run command <code>sudo docker run -it ubuntu bin/bash</code> tries to pull the image again and finally ends up with the message: <code>error response from daemon: No such image: ubuntu (tag: latest)</code></p>
  
  <p>My Ubuntu version: <code>15.04</code> 
  and my docker version details:</p>
