If you know your battery is shot and you don’t have a way to save your install if the power goes out, then you just don’t update. There are plenty of ways to protect against this that have already been mentioned (battery backup, backup kernel, etc). OP was just playing with fire.
That’s kind of overzealous. I would expect most desktop users to run kernel updates without being plugged into a UPS, this is functionally identical. It’s not like it’s an unrecoverable error, but yeah if you’re updating a critical system you should have redundancies in place.
