Maybe give an immutable OS, like Fedora Silverblue or Kinoite a try?
The idea is that it’s very hard to break the system, because apps are containerized, so they don’t ‘touch’ the system, and updates take effect only on reboots.
If update is broken, it won’t apply. And you can always rollback to previous state, if you don’t like something.
You don’t need to install stuff from the terminal, and you can install them from a GUI ‘store’.
