Software Updates Won't Download - EnumerateUpdates for action (UpdateActionInstall) - Total actionable updates = 0

Question

I have a new software updates deployment. I see there are updates that are required on a few clients. The clients work fine with a software package/application, as they download fine with no problems, so it's not a boundary issue. But I can't get the software
updates to work. I keep seeing in updatedeployment.log total actionable updates = 0 even though right above that it is clearly finding new updates.

Answer 1

Anyone have any update to this scenario?
I did a site recovery to new hardware, and subsequently new WSUS version for Server 2012, and am having issues with deploying software updates.  Like the OP above I can deploy applications and packages with no issues.
I've deleted the software update group, recreated and deployed to a collection with machines that do not have these updates installed, since they are this months newest updates.
In the UpdatesDeployment.log I see the following logged:
Software Updates feature is enabled    UpdatesDeploymentAgent    10/16/2013 4:42:58 PM    7288 (0x1C78)

EnumerateUpdates for action (UpdateActionInstall) - Total actionable updates = 0    UpdatesDeploymentAgent    10/16/2013 4:43:18 PM    7400 (0x1CE8)
So it's like it sees the deployment but is not evaluating that it needs the updates.  I'm at a loss of where to look next so if anyone can provide any additional suggestions it would be greatly appreciated.
