title: Job for artifactory.service failed
body: <p>Ubuntu 20.04 LTS
  I just installed oss version if JFrog Artifactory
  To run artifactory I used <code>systemctl start artifactory.service</code> by getting this error:</p>
  
  <pre><code>Job for artifactory.service failed because the control process exited with error code.
  See "systemctl status artifactory.service" and "journalctl -xe" for details.
  </code></pre>
  
  <p>If I run <code>systemctl status artifactory.service</code> this is what I am getting</p>
  
  <pre><code>● artifactory.service - Artifactory service
