software update fails

[OldSmoky2]

The software updater is failing with the following message:
" The following packages have unmet dependencies:
grub-efi-amd64-signed: Depends: grub2-common (>= 2.02~beta2-36ubuntu3.31) but 2.04-1ubuntu35.6 is to be installed"

Have you tried any of these suggestions:

I'd try


sudo apt-get -f install

[MAFoElffen]

Open a terminal:


sudo apt-get install -f
sudo apt-get clean

Then list out the Installed Grub 2 package


sudo apt-cache policy grub2

Post the results, which will show the current installed and any installation candidate...

I just tried apt update and it worked flawlessly. Problem solved. Thank you.
