After standard apt-get upgrade and reboot now I am getting following error when I am trying to run apt-get upgrade in 22.04LTS. What happened here?

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 grub-efi-amd64-signed : Depends: grub-efi-amd64-bin (= 2.06-2ubuntu7) but 2.06-2ubuntu10 is to be installed
E: Broken packages

I had the same issue and sudo apt --only-upgrade install grub-efi-amd64-signed did the trick.

My guess is that this has something to do with your system not using Secure Boot as I can see there's a grub-efi package suffixed with "unsigned"

There's a glitch in the upgrade to grub-efi-amd64-signed and grub-efi-amd64-bin, where they both need to be upgraded, but they depend on each other and neither wants to go first. You could wait for Ubuntu to sort it out somehow, but I was able to fix this problem by using:

apt install grub-efi-amd64-bin

...which forces the upgrade of that one package. (Using the 'install' flag on an already installed package makes it upgrade on its own). Then re-run apt upgrade, and you should find everything else flows again.

Thanks for hints @ruffCode and @jrggv. It looks like unattended upgrade resolved this issue for me overnight.
