After reading that announcement, how can you continue to insist that I am not running Debian Jessie? I appreciate your pointer to adding keys to the Debian security updates repository with apt-key add. I will look into that, however if it were necessary for me to do that manually, I would have expected the <https://www.debian.org/releases/stable/errata> page to have mentioned it explicitly. Perhaps I expect too much... I find the stability of the Debian APT system to be one of the most valuable aspects of Debian Linux, compared to other less stable distributions I have encountered over the years. So I am wary of doing anything to break it, even if it proffered on a Debian web page, as you cautioned. Thank you for sharing your knowledge. Best regards, Larry
