Mostly nothing, but I did have issues once where a package changed but couldn’t be installed due to failing verification as the keyring wasn’t updated. That killed the desktop environment on boot but dropping into the console and updating the keyring specifically before trying the full update again fixed things.

By now there’s an always-enabled service running that updates the keys from time to time. So this wine happen anymore on servers.
