title: Dockerfile and dpkg command
body: <p>I'm trying to create a Dockerfile to install VuFind.</p>
  
  <p>This is my Dockerfile:</p>
  
  <pre><code>#Name of container: docker-vufind:3
  
  # Pull base image
  FROM ubuntu:16.04
  MAINTAINER xxx  "xxx@mail.com"
  
  #Install latest patches
  RUN apt-get update &amp;&amp; apt-get install -y \
      &amp;&amp; apt-get install -y wget 
  
  #Obtain the package
  RUN wget http://downloads.sourceforge.net/vufind/vufind_3.1.1.deb?use_mirror=osdn -O vufind_3.1.1.deb
  
  #Install it
  RUN dpkg -i vufind_3.1.1.deb
  
  #Install VuFind's dependecies
  RUN apt-get install -y -f
  </code></pre>
  
  <p>I launched these commands on my Ubuntu's bash and the software worked fine, but it seems that I can't obtain the same result with the Dockerfile because the dpkg command failed for the lack of the dependencies.</p>
  
  <pre><code>The command '/bin/sh -c dpkg -i vufind_3.1.1.deb' returned a non-zero code: 1
  </code></pre>
  
  <p>Is installing the dependecies (Apache, jdk, php...) before the dpkg command line the only way to create a working Dockerfile or is there a shorter way ?</p>
