title: "Broken packages" do not let me install packages
body: <p>I'm having some problems trying to setup a mjpg-streamer in my raspberry pi running raspbian. When I was trying to install the package, the following error was appearing: </p>
  
  <p><strong>sudo apt-get install libjpeg-dev</strong></p>
  
  <pre><code>Reading package lists... Done

  Note, selecting 'libjpeg8-dev' instead of 'libjpeg-dev'

  <p>I've looked a lot of suggestions on google, and tried things like <strong>apt-get update</strong> and <strong>dpkg --get-selections | grep hold</strong> (nothing shows up). I really tried a lot of stuff, with no luck. </p>
  
  <p>Do anyone have any suggestion on what to do?</p>
  
  <p>Thanks everyone</p>
