Where can I get apt GPG Public keys for older release

lk flag

I would like to install a package from an older ubuntu release into a install of a new ubuntu release, in my case 20.04.

I've added the apt sources list:

deb [trusted=yes] http://old-releases.ubuntu.com/ubuntu/ precise main universe
deb [trusted=yes] http://old-releases.ubuntu.com/ubuntu/ precise-updates main universe
            

This works, and I can install the package, but I would like to remove the [trusted=yes] and actually verify the packages being downloaded.

Where can I find the gpg public keys for older releases (specifically precise), that I can use with apt-key add?

One can find the public keys from the ubuntu-keyring package.

However this will not solve the issue as the keys have all expired, and the verification will fail for this reason.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
