I had a number of problem updating to 10.0.2 and ended up having to do it

I have gone through the TID's for proxy adn updating but my ZCM is not
showing the 10.0.3 update. When I look at the "Configuration - System
Updates" I see only the panels "System Update Overview" and System Update
Staging Groups" not the three panels shown in the documentation. I am
able to see the 10.0.3 update wen I select "Action - Preview Content of
New Updates". I can't select and update to download although the download
update action is available.

I have tried rebooting the server with no change in behavior.

Any clue as to why I'm unable to update.
