My Mid 2013 MacBook Air should be compatible with Big Sur, I believe.

I've loaded the Developer Beta Access utility, after which I see "macOS Beta" on the Software Update panel. I click Upgrade Now. It downloads 9.56GB of files, and then afterwards shows a generic error message. I've tried this 3 times now.

Possible issues with my macbook air?

it has an external USB ethernet dongle.
it has an external monitor
it's set up with BootCamp running Windows 10
It has 33.25GB of free drive space.
It was already running 10.15.6 beta 2.

Any ideas?

Solution: turns out it was the USB Ethernet dongle - I removed that, switched to WiFi, and the download was successful.

Here is the log file I found in Console / Log Reports / Installer.log: Notice the errors "The Internet connection appears to be offline"

I wonder if it is my USB Ethernet dongle? Or are apple's servers just being hammered?

(Sigh - these forums have a very small maximum post limit, so here's a shortened version):
