My Ubuntu (20.04) Software is prompting a new firmware available:
UEFI dbx 77--> 217 (?), but when I try to update I receive the following error message:
Impossible to update UEFI dbx. Blocked executable in the ESP, ensure grub and shim are up to date:/boot/efi/EFI/Boot/shimx64.efi Authenticode checksum [_checksum code_] is presente in dbx.
I am not really sure what this implies and, if I understood it correctly, why is it jumping from version 77 to 217. A bit more of details on the system:
