You may have noticed that Lenny was released this weekend. It seems to me that your /etc/apt/sources.list is probably not set up correctly and that your "security update" is actually a full upgrade to the new stable release. The "no public key" error would confirm that. Please check if your sources.list refers to 'stable' instead of to the codename of the release you want to have installed, which would be 'etch'. If you have not yet actually upgraded any packages, just replace 'stable' by 'etch' in your sources.list, run 'apt-get update', and your system should be fine again. If you do want to upgrade to Lenny, I suggest to first read the Release Notes. Cheers, FJP
