Monkeyman,
You didn't need to uninstall your 64-bit version of Chrome. Instead you could have copied and pasted the two lines associated with the 64-bit Chrome fix, and your updates would have continued.
To get back to a world with Amazon working in a browser, reinstall Chrome via Lite Software. If you run into the same problem with updates not running afterwards, then copy and paste those two lines.
This is not a Linux Lite issue. It's a Google issue that is affecting Debian/Ubuntu based Linux distributions. And it's been going on for a week.
