title: Ambari Server on Ubuntu 18.04: Response 403 while pulling Apache Ambari repository
body: <p>I'm a newbie to Ubuntu. Now I'm trying to install Apache Ambari Server on Ubuntu 18.04.</p>
  <p>I've successfully completed steps like installing jdk, turning off firewall, stopping SELinux. However I came up against an error when running the command to pull Apache repo. The command is:</p>
  <p><code>$ wget -O /etc/apt/sources.list.d/ambari.list http://public-repo-1.hortonworks.com/ambari/ubuntu18/2.x/updates/2.7.5.0/ambari.list</code></p>
  <p>The error was some HTTP response failure with code <strong>403: Forbidden</strong>. I also try another version for ambari (like 2.6.2.0) and even different link for the repo but still the error happened.</p>
  <p>So anyone could tell me what is the problem and how to fix it? Thanks so much for helping me out!</p>
