Installing Ofbiz on Ubuntu

I'm in a process of testing a few open source ERP for a client.

Yesterday I installed odoo without any problem (well, almost ...) because
there were some really good (recent and tested) tutorials.
Today, after may hours, I'm still trying to install Ofbiz.

I know that is probably my fault (because I haven't used the right
procedure). That's why I would like to know if a recent and tested tutorial
exists for installing and running Ofbiz on the Ubuntu platform, and if yes,
could someone recommend the appropriate site where it would be available ?

Thanks,
