Update = After completing troubleshooting, a DELL-Cares agent setup service.
I have an XPS 13 9300 and today (24/9/21) Dell Update identified an update for my network controller driver - Killer 1650/1675 Wi-Fi Controller Driver Version 3.0.1584, A26 (13 Sep 2021) It downloads successfully but then flags it as failed without attempting an install. Looking at the Dell Update activity log it states that the update is unsigned:  Package 'Killer 1650/1675 Wi-Fi Controller Driver' [ [URL] is not signed.    What is the solution to this please?  
Killer 1650/1675 Wi-Fi Controller Driver update reported as unsigned
