Why am I getting an error every time I'm trying to download Big Sur?

Whenever I go to download Big Sur, I get an error message: "Installation Failed — An error occurred while installing the selected updates." I've tried connecting to new networks, deleting the files placed in /Library/Updates and have restarted my Mac more times than I can count. The System Status page says that the Mac Updates should be working correctly; yet, it is not for me. Does anyone else know what I need to do?
