I just hit this case with apt 2.1.10. In my case there are no held
packages (apt-mark shows none).
Apt version:
$ apt --version
apt 2.1.10 (amd64)
The system is in a clean state with 2 packages to be upgraded
(this is on Ubuntu, but it shouldn't really matter):
$ sudo apt upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
gnome-settings-daemon gnome-settings-daemon-common
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded
If I try to full-upgrade the two packages still don't get
installed, but other packages get removed:
$ sudo apt full-upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done

The following packages were automatically installed and are no longer required:
apg fprintd gnome-control-center-faces libcolord-gtk1 libfprint-2-2 libgsound0 libhandy-1-0 libpam-fprintd libsysmetrics1 mobile-broadband-provider-info network-manager-gnome xwayland
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
gdm3 gnome-control-center gnome-initial-setup ubuntu-desktop ubuntu-desktop-minimal ubuntu-session
The following packages have been kept back:
gnome-settings-daemon gnome-settings-daemon-common
0 upgraded, 0 newly installed, 6 to remove and 2 not upgraded.
After this operation, 9.264 kB disk space will be freed.

Same command with debugging info:
