So I want to upgrade from 20.04 to 22.04 LTS.
Ubuntu does this very annoying thing where it forces you to install all your upgrades before it allows you to upgrade your distribution. I've already upgraded once, but I still get
$ sudo do-release-upgrade
Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.
... except, it doesn't let me.
apt seems to know what I need to upgrade:
$ sudo apt list --upgradable
Listing... Done

ok ... I have no idea what this grub-efi-amd64-bin is or why it's been "kept back".
$ sudo apt-mark showhold
$ dpkg --get-selections | grep hold
both don't list anything.
But surely I can upgrade it manually?
$ sudo apt install grub-efi-amd64-bin

A small variation of this issue has been asked before:
grub-efi-amd64-signed dependency issue in Ubuntu 22.04LTS
ruff's answer there is to install grub-efi-amd64-signed ... we just tried that, it doesn't work.
There's another answer by Chen, which suggests
sudo rm /var/lib/dpkg/info/grub*
sudo dpkg --configure -a
BUT I'm not going to do that, for now, as I have absolutely no idea, what that does and in the light of https://ubuntuforums.org/showthread.php?t=1041188 .
Now Unable to correct problems, you have held broken packages suggests
$ sudo aptitude install grub-efi-amd64-signed

And I do admire aptitude's tenacity because there are increasingly wild suggestions after that.
My problem is, I have no idea how to choose a good option. This last one sounds more appealing to me, but what do I know?
Nor do I have any idea what any of these packages' being removed or updated does. The disk is encrypted, and I'd very much prefer not to brick my bloody device trying to upgrade it.
How DO I get to upgrade the bloody OS?
