I am trying to install system update 10.2.1 on my SLES10SP2 server with ZCM 10.2 installed. I have downloaded the update and it says it is Ready, but when I want to "Start Pending State" I get the following error:

Error: Unable to Advance to Next Stage. In order to advance to the next stage, the update must be in a 'Stage Pending' Status. Please recheck the status and try again.

I can't seem to get the update into the pending status.

Could anyone help with this?
