I got this error when running the upgrade on 2021-05-02 as proposed by the system:

grub-efi-amd64-signed:   
  Depends: grub2-common (>= 2.02~beta2-36ubuntu3.31) but 2.04-1ubuntu26.11 is to be installed

I used:

apt list --upgradable to get list of packages that needed to be upgraded:

Listing... Done
grub-common/focal-updates 2.04-1ubuntu26.11 amd64 [upgradable from: 2.04-1ubuntu26.9]
grub-efi-amd64-bin/focal-updates 2.04-1ubuntu44 amd64 [upgradable from: 2.04-1ubuntu26.9]
grub-efi-amd64-signed/focal-updates 1.167+2.04-1ubuntu44 amd64 [upgradable from: 1.142.11+2.04-1ubuntu26.9]
grub-efi-amd64/focal-updates 2.04-1ubuntu44 amd64 [upgradable from: 2.04-1ubuntu26.9]
grub-efi/focal-updates 2.04-1ubuntu26.11 amd64 [upgradable from: 2.04-1ubuntu26.9]
grub2-common/focal-updates 2.04-1ubuntu26.11 amd64 [upgradable from: 2.04-1ubuntu26.9]

And

sudo apt --only-upgrade install grub-common

Updated that package updated everything

    I got lucky and had this issue 3 hours after you posted this answer. It worked perfectly for me. Thank you. – Prime624 May 02 '21 at 19:04
  • The internet is soo fast ;) – rémy May 07 '21 at 06:35
  • Today (2021-05-10) I used: "sudo apt --only-upgrade install grub-common". This was successful. After that, the system did not propose me any further full Ubuntu upgrade. So far so good I guess. Thanks a lot. – Gerardo May 10 '21 at 15:57
  • I encountered the same thing and this fixed it for me as well. Thank you. – Rich Johns Jun 13 '21 at 17:57
  • Sadly this didn't help me. I still get an `Errors were encountered while processing: grub-efi-amd64-signed E: Sub-process /usr/bin/dpkg returned an error code ` – nonNumericalFloat Jan 18 '22 at 19:35
