Downloading macOS less than 1 minute

Less than one minute of downloading for the 15th time and it disconnects and gives error. Now what am I suppose to do?

MacBook Air 11″, macOS 10.15

1 - Made sure you Mac can run Big Sur: macOS Big Sur - Technical Specifications

both for model compatibility and available space.


2 - Try the following:

#1 - boot into Safe Mode according to Start up your Mac in safe mode - Apple Support.

NOTE: Safe Mode boot can take up to 3-5 minutes as it's doing the following; 
• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts 
• Deletes font caches, kernel cache, and other system cache files

#2 - go to the System/Software Update preference pane and begin the download.

#3 - run the installer from the Safe Mode.

I've had better luck from the Safe Mode because I evidently have some 3rd party software that interferes with the installation.
