body: <p>I hired a VPS with Ubuntu Server 12.04.4 LTS <b>minimal</b> for test development in symfony2 and want to install Zentyal for taste it too.</p>
  
  <p>This is what i have tried from base Ubuntu installation:</p>
  
  <p><code>apt-get install python-software-properties</code></p>
  
  <p>Adding universe repository:</p>
  
  <p><code>add-apt-repository "deb htt...archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"</code></p>
  
  <p>Added Zentyal repository "deb htt...archive.zentyal.org/zentyal 3.4 main extra" with nano in /etc/apt/sources.list</p>
  
  <p>Adding public keys for Zentyal:</p>
  
  <p><code>apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 10E239F<br>
  wget -q htt...keys.zentyal.org/zentyal-3.4-archive.asc -O- | sudo apt-key add – </code></p>
  
  <p>Updating apt:</p>
  
  <p><code>apt-get update</code></p>
  
  <p>And installing Zentyal:</p>
  
  <p><code>apt-get install zentyal</code></p>
  
  <p>All this results, that have no avaible dependecies like <b>zentyal-core</b> and <b>zentyal-software</b>.
  <b>zentyal-core</b> depends of <b>haproxy</b> which depends of <b>init-system-helpers</b>, and when i try to install this last dependence, I find the message:</p>
  
  <blockquote>
    <p>Package init-system-helpers is not available, but is referred to by another package.<br>
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source</p>
  </blockquote>
