Eduardo! Welcome in our community, happy to see another Brazilian guy. Where in the world are you?
Have you tried to install them on NethServer/CentOS yet?
I can introduce you to the Brazilian people who’re active here (also in your language) would you like? We have numbers to organize also a meetup directly in Brazil or at least online

Do you think that a Portuguesesection could help?
Your English is very good, compliments!
Get back to me if you need, glad to help.
