Just want to inform everyone that I got Openbravo ERP to work with Linux Mint. I updated the below installation guide to include Linux Mint:

Openbravo installs the easiest with Debian-based distros. Linux Mint makes it easier since by default, it uses Ubuntu's Multiverse repository. This is a great way to present Linux Mint to the business community which is what I will do with my clients this week.
