Software updates usually are problem free but I'm getting this one.
My older desktop runs Ubuntu 20.04.2 LTS
This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.
Transaction failed: Package dependencies cannot be resolved
The following packages have unmet dependencies:
grub-efi-amd64-signed: Depends: grub2-common (>= 2.02~beta2-36ubuntu3.31) but 2.04-1ubuntu26.12 is to be installed
