Upgrading problems with Xoom from 4.1.1 to 4.1.2

I have a Xoom wifi with 4.1.1 installed. Under Settings/about Tablet, it indicates Android version 4.1.1. I have clicked System updates many times and it indicates Up to date. I have seen the machine download and apparently try to install the newer 4.1.2 a few times. It even goes through a series of steps shutting down the machine and starting it up again but it never seems to complete the install. It keeps on indicating version 4.1.1.

Any thoughts?
