This error surfaced because Heroku's verification key expired. Nothing can be done until Heroku releases updated keys, which may take a few days.

Edit: Currently, it appears they have published updated keys, and all that remains is to:

curl https://cli-assets.heroku.com/apt/release.key | sudo apt-key add -
