I updated according to the server alert, and now I'm getting continuous server alerts saying a module has failed:
This module is required by cPanel, and the system may not function correctly until it is installed, and functional. Below is the results of the auto-install attempt:

My advice is to let KH support handle the update by issuing a support ticket.
