Update: Gave up on the download and stopped it. I've cleared the Download list and have started afresh.
Well, I got the right download et cetera but, as previously, at the point where I enter ‘y’ in Terminal to erase the thumb drive, I get an error message: “Failed to start erase of disk due to error (-9999-0)”
Have you tried to simply run the included installer to see if it will upgrade you from Snowy (without erasing your drive)?
