    This morning my 2017 mbp updated went to restart. Then I got this message on the screen. I tried restarting it many times but it's still stuck.

    Any ideas on how to fix this other than formatting it?

    Also there are no apple stores where I live so it's not an option.

    Hold CMD + R on startup, select Reinstall macOS. This won't wipe your data, just reinstall the core OS. Hopefully this should fix the problem.

    Do you have the App Store setting (system preferences) set so that updates are automatically downloaded and installed?

    If so, I would UNcheck the "automatic install" option.
    I don't mind being notified that updates are available, but...
    I want to install them "manually" -- so I know what's going on.
    I don't like updates "installed behind my back".
    That can produce unexpected results -- like those you had above.
