Updates to 9.1-2 performed via the UI may fail.
The appliance UI may time out before it has finished updating to 9.1-2. After the UI is refreshed, error messages will appear, but the appliance will indicate that it is now on version 9.1-2. This misleads the user into believing that the appliance has been updated successfully. If the user reboots the appliance, duplicate rpms will be left on the system.
Fixed in 9.1.1.
The UI is prone to disruptive timeouts during the update process.
