title: vnc server cannot apply subscription
body: <p>I installed VNC server on my Ubuntu 18.04 pc, however I cannot enable the cloud connectivity. As per the docs I need to run commands with <code>sudo</code> to start the VNC server in service mode. So I tried this command:</p>
  
  <pre><code>sudo systemctl enable vncserver-x11-serviced.service
  </code></pre>
  
  <p>But when I try to login to the VNC server desktop application, it says <code>"Administrative privileges are required for this operation"</code></p>
  
  <p>What am I doing wrong here?</p>
  
  <p>Thanks</p>
