I don’t think you need to wait years for user friendly Linux tbh! I recommend checking out Linux Mint. It’s basically designed for people used to Windows and handles the technical stuff for you.
You can do almost everything through the GUI rather than the command line, so for things like updates, it’ll show you a little notification in the corner by the clock like you’re used to, you open up the software manager, and click the update button.
And most software nowadays can either be downloaded through an app store like interface, or by downloading an executable file from a website.
And if you’ve ever used a mac, there’s a time machine equivalent built in (timeshift). So you can set up an automatic backup daily/weekly/etc and if you mess up something, in most cases you can revert back to a point when it wasn’t messed up.
I say give it a shot, you can always go back if it’s not for you! But usability has improved so much in the last few years.
Ah, so Seagate still sucks!
