Strange error update message

[aughey]

Just got this fault message on my 20.10 laptop. Havn't a clue what it means but nothing was installed.

I saw the same yesterday from Software Updater. What I did was some terminal stuff. From the terminal history:
1) hold this offending package:

sudo apt-mark hold grub-efi-amd64-signed*
2) upgrade the rest:

sudo apt-get update
sudo apt-get upgrade
3) remove the hold on the package:

sudo apt-mark unhold grub-efi*
4) upgrade again:

sudo apt upgrade

Upgrade completed without further error.

Many thanks Dennis N
