1. Please update version
2. Does this change have Backward compatibility?

[anoliveiraM]

@okopel , just changed the script version also in terms of compatibility since we are checking and installing gnupg and using it it should be backwards compatible on their docs there's nothing that would not indicate so:

The current method we have in the code will fail with most recent OSs :(
