I had the same challenges as masipay when I started using GNU-Linux. I feel
the same as Fernando; it wasn't always easy but I'm glad that I kept trying.
Documentation is so much better today than it was even just eight years ago.
Especially because Ubuntu has become so popular.
I did a quick search for your issue masipay; does this help? Well I guess
it's too late this time, but if you give free software another try in the
future, maybe keep these handy:

There seemed to be some video tutorials in the search results too btw.
