title: Oracle Net Configuration Assistant failed
body: <p>After installing Oracle Linux 6:</p>
  
  <pre><code>uname -a
  Linux ponos 2.6.39-400.109.1.el6uek.x86_64 #1 SMP Tue Jun 4 23:21:51 PDT 2013 x86_64 x86_64 x86_64 GNU/Linux
  </code></pre>
  
  <p>and making sure that all the pre-required packages are present, I downloaded "Oracle Database 12c Release 1 (12.1.0.1.0) for Linux x86-64", followed the pre-installation instructions and launched the installer.</p>
  
  <p>The installer runs smoothly up to the "Execute Root Scripts" step.</p>
  
  <p>During the "Oracle Database configuration", the "Oracle Net Configuration Assistant" throws error:</p>
  
  <p><strong>[INS-20802] Oracle Net Configuration Assistant failed.</strong></p>
  
  <p>The error log is empty:</p>
