Added some info on how to install gpg on debian 12

[coudot]

Hello @elecharny, gpg package seems available on Debian 12: https://debian.pkgs.org/12/debian-main-amd64/gpg_2.2.40-1.1_amd64.deb.html

@coudot 'seems'. But when you do a fresh debian 12 install followed by a 'gpg' install, it gives you that error message:

# apt install curl gpg
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package gpg

Actually to have gpg installed, I had to do that:

#  apt install gnupg2
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following additional packages will be installed:
  dirmngr gnupg gnupg-l10n gnupg-utils gpg gpg-agent gpg-wks-client gpg-wks-server gpgconf gpgsm libassuan0 libksba8
  libnpth0 pinentry-curses
...

Now, why is apt install gpb not working is a mystery to me...
