I upgraded my Thinkpad laptop from Ubuntu 20.04 to 20.10. All went well. However, there's now firmware updates available but when I try to apply them I get an error saying:
Unable to update "System Firmware": missing signed bootloader for secure boot: /usr/libexec/fwupd/efi/-fwupdx64.efi.signed can not be found
How do I fix this so I can update firmware? Shouldn't this be taken care of during the system upgrade?
