Not sure what's up with the Calamares logs, but the full error is:
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-bin : Depends: grub-common (= 2.04-1ubuntu37) but 2.04-1ubuntu40 is to be installed Recommends: efibootmgr but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
This is the result of trying to install grub-efi-amd64-signed. src:grub2 and src:grub2-signed have been released (as 1ubuntu40) as of the 25th and efibootmgr hasn't changed in forever. Something is weird here with regards to packages.
