  <p>I am trying to install Ambari 2.5.2.0 following the steps indicated in 
  <a href="https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.2.0/bk_ambari-installation/content/ch_Getting_Ready.html" rel="nofollow noreferrer">https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.2.0/bk_ambari-installation/content/ch_Getting_Ready.html</a></p>
  
  <p>I use Ubuntu 14 and my Internet access is through a proxy. </p>
  
  <p>I have tried the following two configurations: 1.embedded PostgreSQL, and 2. a standalone PostgreSQL. In both cases, I have the same error when I start Ambari server. The error message displayed on the screen is the following:</p>
  
  <pre><code>Server PID at: /var/run/ambari-server/ambari-server.pid Server out at: /var/log/ambari-server/ambari-server.out Server log at: /var/log/ambari-server/ambari-server.log Waiting for server start.........Unable to determine server PID. Retrying... ......Unable to determine server PID. Retrying... ......Unable to determine server PID. Retrying... 
  ERROR: Exiting with exit code -1. REASON: Ambari Server java process died with exitcode 1. Check /var/log/ambari-server/ambari-server.out for more information.
