I've been trying to download the Big Sur for a month but after so many tries the same message shows up '' An error occurred loading the update '' .

I have 36.06 GB free space on my storage , and the 12.23 GB Big Sur Installer is already downloaded !!

And i have a fast internet connection on my Macbook Air 13 2017 .

What is needed to get the new Update ?
