That would likely be caused by a malfunctioning Mojave system or a drive problem. For the latter, you can try this:
Repair the Drive for El Capitan or Later
Try your upgrade once again. If this doesn't fix the problem, then you have two options.
A current backup of your files is essential before doing either.
Reinstall El Capitan or Later Without Erasing Drive
Please be sure you back up, if possible.
Install El Capitan or Later from Scratch
If possible, back up your files.
