Recently installed Linux Mint, what baffled me in 2022 is that regularely upon log-on it nags me to install security updates and when I acknowledge the request, it asks me for my password again. I agree that general package manager operations should be a privileged operation... but approving the installation of security updates should not have the user being greeted by just another password prompt.
They're exactly the same filesystem operations, it's just the semantics of why they're being installed that changes.
What frustrates me about updates is that they nag at log-in when I've already been waiting for the computer to boot and just want to get on with the task at hand.
