title: Docker service does not start
body: <p>docker is gigving me a hard time currently. I followed these <a href="https://docs.docker.com/installation/ubuntulinux/">instructions</a> in order to install docker on my virtual server running Ubuntu 14.04 hosted by strato.de.</p>
  
  <pre><code>wget -qO- https://get.docker.com/ | sh
  </code></pre>
  
  <p>Executing this line runs me directly into this error message:</p>
  
  <pre><code>modprobe: ERROR: ../libkmod/libkmod.c:507 kmod_lookup_alias_from_builtin_file() could not open builtin file '/lib/modules/3.13.0-042stab092.3/modules.builtin.bin'modprobe: FATAL: Module aufs not found.
  Warning: current kernel is not supported by the linux-image-extra-virtual
   package.  We have no AUFS support.  Consider installing the packages  linux-image-virtual kernel and linux-image-extra-virtual for AUFS support.
  </code></pre>
  
  <p>After the installation was done, I installed the two mentioned packages. Now my problem is that I can't get docker to run.</p>
  
  <pre><code>service docker start
  </code></pre>
  
  <p>results in:</p>
  
  <pre><code>start: Job failed to start
  
  
  docker -d
  </code></pre>
  
  <p>results in</p>
  
  <pre><code>INFO[0000] +job serveapi(unix:///var/run/docker.sock)

  <p>and</p>
  
  <pre><code>docker run hello-world
  </code></pre>
  
  <p>results in</p>
  
  <pre><code>FATA[0000] Post http:///var/run/docker.sock/v1.18/containers/create: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?
  </code></pre>
  
  <p>Does anybody have a clue about what dependencies could be missing? What else could have gone wrong? Are there any logs which docker provides?</p>
  
  <p>I'm searching back and forth for a solution, but couldn't find one.</p>
  
  <p>Just to mention this is a fresh Ubuntu 14.04 setup. I didn't install any other services except for java. And the reason why I need docker is for using the dockerimage of sharelatex.</p>
  
  <p>I'm thankful for any help!</p>
