not sure why it even kicked off but its been "In Progress" for several days

I tried the client.acu approach and the PS script that forces an update.

Nothing works, still "In Progress"

Hi,

Have you seen this KB?

FIX: The content status of a package is stuck in "In progress - Waiting for Content" status in System Center 2012 Configuration Manager SP1

Yes, I know this is an old post, but Im trying to clean them up. Did you solve this problem, if so what was the solution?

Since no one has answer this post, I recommend opening  a support case with Microsoft Customer Support Services (CSS) as they can work with you to solve this problem.
