Secure Boot Setting Can Affect fwupdate Commands on Intel-Based Network Controllers (32355015, 32409181)

On systems running Linux, when Secure Boot setting in the BIOS Setup Utility is enabled, fwupdate will not be able to see information on Intel-based network controllers. If fwupdate cannot detect information on a device, it cannot update its firmware.

Note:

If you encounter this issue, you might also see an "MMIO memory settings" warning message even if you performed the workaround described in Linux MMIO Kernel Configuration Can Affect fwupdate For Intel NIC/LOM Updates (25736189, 26006365, 25654252). In this case, you will also need to perform the Secure Boot workaround.

Workaround

Go into the BIOS Setup Utility and under the Security menu disable Secure Boot. Then restart the system, perform any firmware updates, and re-enable Secure Boot in the BIOS Setup Utility.
