title: esxcli software install returns with Error: Unknown command or namespace software install
body: <p>When attempting to load a vib onto an ESXi 6.5 installation </p>
  
  <pre><code>[root@myserver:~] esxcli software install
  </code></pre>
  
  <p>I get the error:</p>
  
  <pre><code>Error: Unknown command or namespace software install
  </code></pre>
  
  <p>Has anybody seen this error and is it a setting that I am just missed and can get past.  I thought it was an error and I reloaded the hypervisor to a slightly newer version, however I'm getting the same error. Seems like I am missing something simple, however I'm not sure.</p>
