Due to a bug in apport's method for creating a duplicate signature, the DuplicateSignature in this report was incorrect. We are fixing that now, sorry for the noise!

This looks like you have a system that was previously installed in UEFI mode, but you have removed the ESP from /boot/efi and booted it in BIOS mode instead. Is this the case? Is there a reason you have done this?
