title: Cannot install Docker on Debian Jessie
body: <p>Despite trying both the official installation mechanism using the new apt repo described <a href="https://docs.docker.com/engine/installation/linux/debian/" rel="noreferrer">here</a>, as well as the <code>curl -fsSL https://get.docker.com/ | sh</code> route, I still get <code>E: Unable to locate package docker-engine</code> from APT when I try to <code>apt-get install docker-engine</code>. </p>
  
  <p>My versions are:</p>
  
  <pre><code>$ uname -a
  Linux blah 4.5.5-x86_64-linode69 #3 SMP Fri May 20 15:25:13 EDT 2016 x86_64 GNU/Linux
  
  
  $ lsb_release -c
  Codename:       jessie
  
  $ cat /etc/debian_version
  8.5
  
  $ cat /etc/apt/sources.list
  deb http://ftp.uk.debian.org/debian/ stable main contrib non-free
  deb-src http://ftp.uk.debian.org/debian/ stable main
  deb http://security.debian.org/ stable/updates main
  deb-src http://security.debian.org/ stable/updates main
  deb http://http.debian.net/debian wheezy-backports main
  </code></pre>
  
  <p>The only file in my <code>/etc/apt/sources.list.d</code> is <code>docker.list</code> which contains:</p>
  
  <pre><code>deb https://apt.dockerproject.org/repo debian-jessie main
  </code></pre>
  
  <p><code>apt-cache policy docker-engine</code> doesn't find it either:</p>
  
  <pre><code>apt-cache policy docker-engine
  N: Unable to locate package docker-engine
  </code></pre>
  
  <p>How might I resolve this?</p>
