Core issue

This error occurs because the Cisco Clean Access (CAS) never receives the updated agent updater package from the Cisco Access Manager (CAM).

Resolution

In order to resolve this issue, try these workarounds:

1. Uninstall version 4.0.1.0 first and then upgrade to 4.0.2.0.
   
   
2. With the CAM/CAS 4.0.3/4.0.2.0 Agent, the CCAAgentUpgrade-4.0.2.0.tar.gz must be downloaded from Cisco Secure Downloads and uploaded to the CAM through Device Management > Clean Access > Clean Access Agent > Distribution.
