Linux

Unsure if you're being serious or not. Or if this is just bait. So I apologize in case I just got whooshed.

There's a decent amount of distros that don't require you to ever operate a terminal. Updates either

• happen automatically in the background
• Or, you're prompted for an update and can choose to run it
• Or, within settings or a dedicated app, you can press a button to initiate the process of updating

Furthermore, most distros that are recommended for beginners don't need regular updates anyways.

Updating isn't the only part that has been taken care of by this set of distros. Linux has become pretty smooth sailing overall.

Notable exceptions to the above are mostly tied to some janky/troublesome hardware setup. Or, if you'd like to run software that isn't easily accessible. In those cases, while a GUI-only solution may exist, it's simply a lot easier for all involved parties if a terminal solution is offered instead:

• it works on most distros; irrespective of version, DE, base distro or whatsoever. So, the one providing a solution doesn't have to create over a dozen of distinct solutions to cover all bases
• these methods tend to change a lot less frequently. Sometimes solutions are tied to DEs, and these may change how they organize stuff over time. So, terminal solutions have better longevity
• instead of moving through dozens of menus/toolbars/buttons or whatsoever, you literally copy and paste a couple of commands and you're done. I would prefer the terminal any day

OP, you did get me curious, though. Which distro do you use?
