  </code></pre>
  
  <p>As seen in debug messages after "Please wait..." no installer window opens and there are further messages that is displayed in the console and then it is always like that. I have verified the logs in <code>/tmp</code> directory and it appears to be clean. I am stuck with this issue since long and do not know how to proceed.</p>
  
  <p>Please guide.</p>
