Hello JoelinHouston,
Thank you for using Apple Support Communities!
It is our understanding from your post that you are receiving a message that installation failed when updating to macOS Big Sur. We recommend installing macOS Big Sur while your Mac is in safe mode. The following articles have the steps you will need to restart your Mac in safe mode:
How to use safe mode on your Mac - Apple Support
"Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed."
Best Regards.
