Updating the "extra" repository breaks the Danctnix OS

[Evergreen]

So, I'm new to Arch. Might be more of an Arch question, but here goes:

I recently broke my OS by updating a bunch of stuff from the "extra" repos. When I ran the following to update:

Code:

sudo pacman -Syu

It asked me if I wanted to basically reinstall a bunch of already installed packages via the "extra" repository. I was tired of seeing that prompt, so I finally just said yes to everything. After that, the OS wouldn't boot. I did this twice actually. Same thing happened.

I successfully reinstalled the OS, I just don't want to make the same mistake a third time.

How do I either avoid breaking the OS with extra or make sure that the prompt isn't annoying me all the time?

Thanks,
Evergreen
