Apple has confirmed the issue with downloading macOS Big Sur on its System Status page saying “Users may not be able to download macOS Software Updates on Mac computers. The issue is currently being investigated.”
Even after Apple sharing the macOS software update problem has been fixed, users are still seeing an error after Big Sur is downloaded preventing it from being installed. It looks like it will take more time before this is fully ironed out.
