I don't know. I know that local cdroms need a config to tell apt that they are trusted. But I didn't think that file:/ directories needed that configuration. Perhaps they do. > I guess only this is remaining everything else seems to be sorted out. Good. Pretty close then. This is one of those things that works-for-me. Making it hard for me to deduce why it isn't working for you. The Release.gpg file is signed with the Debian Archive Keyring. APT verifies the signature on that file. That file contains the file check sums of the packages. That is the security chain. If APT can't verify the chain then it produces the warning. WARNING: The following packages cannot be authenticated! Something in that chain is broken for you. But I can't guess what. Bob
