title: Error while installing Oracle 11g on Ubuntu server 14.04
body: <p>I am trying to install Oracle 11g R2 on Ubuntu 14.04 64-bit using the "silent" installer. I am using .rsp file with the process but getting this error:</p>
  
  <pre><code>[WARNING] [INS-06101] IP address of localhost could not be determined
     CAUSE: The localhost is not mapped to a valid IP address in Hosts file (Eg. /etc/hosts in Unix).
     ACTION: Assign a valid IP address for the localhost or set it to loopback IP address (127.0.0.1 in IPv4 or ::1 in IPv6).
     SUMMARY:
         - ip-172-30-0-89: ip-172-30-0-89
  P.S. I still don't have a domain name for the server.
  </code></pre>
  
  <p>Thanks</p>
