Firmware Update 20211111

Tried an update but got missing signed bootloader for secure boot: /usr/libexec/fwupd/efi/fwupdx64.efi.signed cannot be found. This is a Secure Boot issue, so reboot to BIOS and turn Secure Boot off. Then redo the update, reboot, redo the update, reboot, etc until no more updates available. It seems we had to loop to get all the updates. From the BIOS Secure Boot was then re-enabled.
