Hello Bigbiz! Thanks for you reply!
Actually I had already tried that... But it gave me the following output:
root@host:/# apt-key adv --keyserver hkp://keys.gnupg.net --recv-keys 7D8D0BF6
E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation
So then I tried to install gnupg, but it generates a lot of errors (due dependencies problems) and broke my WLS and I need reinstall it (three times).
Do you know if is there other way to install gnupg for Kali WLS? I mean, I know there is, but I don't know how.
