Hi Larry, That's Raspbian - NOOBS installs Raspbian. As Lisi Reisz has stated to you in another email: Raspbian handle their own security updates. If you want to add the keys to the Debian security updates repository you can use an apt-key add command and the key available from http://ftp-master.debian.org/keys.html [The main archive signing key is also used to sign the security updates]. Be aware that you might create problems for yourself. You may well want to look at the Debian Administrators handbook - you can try apt-get install debian-handbook if the package is also available for Raspbian. Hope this helps, Al the very best, AndyC [Copying to the list as this may be of more use more widely]
