Trying to update my mom's 2020 MacBook Air from Big Sur to Ventura and it keeps failing. "Installation Failed. An error occurred while installing the updates." It has plenty of disk space (188 GB). What I've tried so far:

Reboot the MBA.

Boot into Safe Mode.

Reset PRAM/NVRAM.

Downloaded over wifi.

Downloaded over ethernet.


Does anyone have any ideas on what to do here that I haven't tried?
