How do I open BleachBit 2.0 as root on Ubuntu 18.04.1 LTS?

Forums: 

It used to work but something has happened to it and now it does not work. I click on the icon, type in my password, and BleachBit 2.0 never opens. The regular non root version works just fine.

BleachBit version: 
2.0
Your operating system: 
Ubuntu 18.04.1 LTS
