From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I sympathise with your Dad - everyone's had updates go bad, and it's easy to assume the "don't fix what ain't broke" mantra. But to do so is being willfully ignorant of basic computer security. And to be fair, Debian-stable is one of the least troublesome things to just let automatically update.
Debian and Ubuntu have the unattended-upgrades package which is designed to take a lot of the sting out of automatic updating. I'd recommend setting that up and you won't have to touch it again.
There's also the crontab way - "apt-get update && apt-get upgrade" at frequencies that suit you. (A check for reboot afterwards is a good idea).
For the crontab I think maybe: "apt-get update && apt-get upgrade --assume-yes"
But what about flatpaks?
Since we're talking Ubuntu, I'd add
"flatpak update" and "snap refresh" to the cron
