I just installed a new Debian 9 system on a reformatted disk in a multidisk
system. I used the Netinstall cd from Debian. Installation went ok and I am
sending this from the system. Problem is I tried to add the contrib and
non-free repos to synaptic i.e. apt sources.list I simply copied the
sources.list file from a current working system that has no issues. The message
below is what I get when I try to run apt update:

I have used Debian for years, and dont often use this list but this is a new
issues to me and though I can find a lot of info, I have not found a solution.
i did download the current keyrings and installed them, but that did not help.
Just wondering if this is some new issue related to secure apt.ThanksJohn
