I'm running 22.04.2 LTS, and I have a message in the Software Update tool it says I have a firmware upgrade to install: "Secure Boot dbx Configuration Update" (Version 77 -> 217).

Whenever I try and do this using the GUI, it hangs and I'm then unable to shut down my machine. I have tried some basic terminal instructions, with similar effect.

Why am I unable to update the "Secure Boot dbx Configuration Update"?

Running sudo fwupdate -l gives the following:

failed: Error opening file /sys/firmware/efi/efivars/FWUPDATE_DEBUG_LOG-0abba7dc-e516-4167-bbf5-4d9d1c739416: No such file or directory

Running sudo fwupdate -i gives the following:

(fwupdate:19008): FuPluginUefiCapsule-WARNING **: 17:06:18.722: SMBIOS BIOS Characteristics Extension Byte 2 is invalid -- UEFI Specification is unsupported, but /sys/firmware/efi exists: System does not support UEFI mode Information for the update status entry 0: Firmware GUID: {ffd4675e-ff47-46d9-ac24-8b331f937737} Update Status: No update info found

    @richbl Look into edit history ;-) I removed it. That was a complete crap. Now it is a good question ;-)

It looks like there are problems with fwupdate.

It could be that you started the update, didn't let it finish and restarted the PC.

Also there may be other problems. The best choice in this case is to download BIOS from the PC vendor site and upgrade it according to vendor's manuals.
