I'm running Zenworks Configuration Management version 10.3.0.0 and am trying to update, but am unable to.
The following updates are available:

Update for ZCM (10.1.1) - status: baselined
Update for ZCM (10.1.2a) - status: baselined
Update for ZCM (10.1.3) - status: baselined
Support Pack 2 for ZCM (10.2) - status: baselined
Update for ZCM (10.3.0a) - status: Canceling

I'm stuck here. The update for ZCM 10.3.0a cannot be deleted or deployed because it is "canceling" and has been doing this for several weeks!

What is the correct way to update my ZCM server?
