Like I said, the installer has a bug. Softwares have bugs and installers are softwares. Installer bug can happen on Windows, Linux, and probably macOS too.

The obligation of the OS is to stop the installer when potentially unwanted behavior is detected. And the store and terminal are both doing that. The store even tells linus that this will likely be fixed later, and he can try again.

So I personally don’t see what more reason the store can provide than “this installer is trying to remove essential software, try again later”. Maybe the developer can be more specific to say that “this can brick your system”, “remove your desktop environment”, or “you will be booted into a terminal”, but I doubt an average users will know what that means either.

A big reason people see less software bugs on Windows is because more people are using it and reporting bugs. This is why many linux user are tirelessly (perhaps annoyingly, to some) preaching Linux. Because getting more user to Linux is the only way to ensure our future of stable and free softwares.
