It appears from the screen shot you've provided that you're using Hue in the Cloudera Quickstart VM on top of Oracle VirtualBox. Can you tell us a bit more about why you're attempting to use the Cloudera Quickstart VM? Can you specify which set of instructions you are following or which Hue tutorial is guiding you?
As of this writing, I don't believe that there are many people still running the Cloudera Quickstart VM, and for that reason, I think it's unlikely that anyone will be able to help you with the specific error you're encountering while attempting to create your desired dashboard. While we welcome your question, and it will remain visible here in the hope that some member of the Cloudera Community will answer it, you would be much more likely to obtain a suitable solution if you focus your efforts around a more up-to-date data platform.
