MATLAB: How to activate Live Editor in Ubuntu 18.04

live editorubuntu 18.04

I installed MATLAB 2019a in Ubuntu 18.04 today. Installation was successful but when I was trying to create a Live Editor script, MATLAB responded with "Live Editor is unable to run in the current environment". After clicking on "Live Editor Requirements" link, I was advised to contact Technical Support for instructions on how to configure the system environmen. Please provide me with this information.
Thank you.
