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:

sudo fwupdate -L; sudo fwupdate -i
command.
