Linux has its conveniences but I think I definitely spend more times on updates. Some break things and some like Nvidia's drivers can take me ages to actually apply (though with that one the usual trick seems to be to remove --purge nvidia-* first).
That depends on which distro and hardware you're using. I use laptops that are known to work well with Linux and Ubuntu LTS releases. This way, I spend perhaps 3-5h a year on admin tasks and it's mostly easy stuff.
It's actually amazing how GNU/Linux allowed me to gradually transition from configuring everything (when I was a student: XFree86, custom kernels, ...) to using GNU/Linux productively with almost zero housekeeping effort.
You can even try Silverblue. On the off chance something breaks, i do an rpm-ostree rollback, reboot and the system is on it's previous working state. I could troubleshoot stuff If I want to but I usually wait for an upstream fix before I update again.
I wanted to like silverbluez used it on the homelab as a host os for a while, went back to a normal server in the end, way less hassle.
Depending on what you want to do, you use the appropriate version.
Indeed if one is not willing/able to climb the learning curve of this paradigm shift, then they shouldn't use it.
I get why maintainers want to push flappypacks, I just don't care, it's a shit solution that leaks all over your users. Find a better way to fix your problems.
A hardware and software config + the goal (print)- and a dialog pops up, offering your solution as a line by line shell script.
All this stored in a trustworthy DB and even complex problems could be plug and play on windows. Add a "support" button to finance the whole thing.
Voila. Year of the linux desktop.
You might want to look into something less unstable.
I've had arch running unattended upgrades in a Cron for years.
Worst case I have to find my USB stick and do some debugging, not that an update has ever broken anything.
There is some minor maintenance I run maybe once every 6-12 months to clear caches or fix up any configs that need updating but I've never run into anything that prevents booting.
