The updates you are trying to apply are not Dell-authorized updates

If you get the error "The updates you are trying to apply are not Dell-authorized updates" on a Dell Poweredge server when trying to update firmware with the Lifecycle Controller (F10) option, you need to update the DRAC and LC firmware through the DRAC gui (or with RACADM).

You need:

iDRAC – at least version 1.85 or newer

Lifecycle Controller – at least version 1.5.2 or newer
