title: Ubuntu 16.04: Oracle JDK 9 is NOT installed
body: <p>Every time I try to install something from terminal this message pops up to me. Meanwhile I have my Java installed right:</p>
  
  <pre><code>download failed   
  Oracle JDK 9 is NOT installed.  
  dpkg: error processing package oracle-java9-installer (--configure):
   subprocess installed post-installation script returned error exit status 1  
  Errors were encountered while processing:  
   oracle-java9-installer  
  E: Sub-process /usr/bin/dpkg returned an error code (1)
  </code></pre>
  
  <p>Please can someone help me solve this; it's really annoying.</p>
