Environment

VMware vCenter Server Appliance 6.0.x

Cause

This issue occurs when IPv6 is disabled on the appliance which prevents the update from proceeding.

Resolution

Enable IPV6 in vCenter Server Appliance before updating.
 

Note: Before enabling IPv6 in vCenter Server, roll back the failed upgrade because it does not rollback automatically.
