Public bug reported: There is a grub2+grub2-signed SRU in eoan-updates that is failing to install here. The publication all looks correct, and 'apt upgrade' or 'apt dist-upgrade' show no problems, but update-manager repeatedly shows:
"Package dependencies cannot be resolved This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.
