Package: debian-handbook Version: 8.20170125 Severity: normal Dear Maintainer,
man APT-KEY(8) on stretch for the "add" command says "Note: Instead of using this command a keyring should be placed directly in the /etc/apt/trusted.gpg.d/ directory with a descriptive name and either "gpg" or "asc" as file extension." but "The Debian Administrator's Handbook" and https://www.debian.org/doc/manuals/securing-debian-howto/ch7 still say to use apt-key add. -- sergio.
