I found out an easier way to make it so.
As commands must be issued as root, first get into root mode:
simply
su
if you use the NOPASSWD flag into sudoers or your account, you can use this:
sudo su
Than paste this, line by line:
apt-get install debian-keyring apt-transport-https dirmngr
gpg --recv-keys 1CE63BD7D117204E | gpg --export 1CE63BD7D117204E | apt-key add -
exit
