Google Calendar / Google Apps integration with Thunderbird, seems to be a simple task to accomplish don't you think?

This is the second or third time this has happened to me therefore I thought I'd share this with you guys!

Well, I had an experience with one of my colleges today having to install Thunderbird + Lightning + Google Provider on Ubutnu 9.04 and I tell you it wasn't that straight forward.

The recipe is supposed to be quite simple if you want an external calendar in your Thunderbird you need lightning, if you want to integrate a Gmail calendar with your Thunderbird you need Google Provider.
