I have an update from Dell for my laptop (see screenshot below). When I click on "Restart & install", it does shutdown/reboot the computer, but the update is never applied.
What am I doing wrong? Is there an alternative command that I can run to apply the update?

This is a special class of updates called "Firmware Updates" which affect your BIOS and system firmware on the system board. These typically come from Dell and hardware manufacturers, and typically firmware updates like this do not get applied during a warm boot (aka a "reboot").
You typically need to do what is called a 'cold boot' - a full shutdown and then turn on the computer again from that cold 'powered off' state - for the firmware to pick up on the fimrware update needing installed. During that process it'll see it has a pending firmware update and apply it.
(This is the case on my XPS 15 9570 and likely other XPS/Precision models)
