Specifically, the lenny release file is signed with key 473041FA. You can also retrieve this key from a keyserver network with commands like:gpg --recv-keys 473041FA gpg --export -a 473041FA | sudo apt-key add -
We should stop using 32-bit keyids. Generating another OpenPGP key with keyid 473041FA is not really computationally expensive.
