As I intend to distribute some of my utilities, I had these doubts:
Is the English version of the GPL valid in non-English speaking countries?
Do I need to translate the GPL when I include it in my software?
On the official website it has the following:
Are there translations of the GPL into other languages?
It would be useful to have LPG translations in languages other than English. People even made translations and sent us. But this carries such a risk that we dare not accept it.
In addition:
An unapproved translation has no legal force, and it should explicitly state this
So, I was in doubt, I do not know if an English license would be valid, and apparently a Portuguese license needs to be approved by GNU staff before having some kind of validde.
What to do in this case?
I found this question: How software licensing works in Brazil
But she does not answer my question.
