Basic Secuity Setup

I’m trying to setup Basic Security, When I run hciupgradeutility I get the following error.

Can anyone assist in how I set X11 DISPLAY variable?

Does this command have to be run from the console?

-bash-3.00$ hciupgradeutility

java.awt.HeadlessException:

No X11 DISPLAY variable was set, but this program performed an operation which r

equires it.
