Strange "Can't guess meta-package" error message when run Software Updater

Ubuntu 22.04.4, GNOME 42.9, Wayland.

When I run the Software Updater, I started getting the series of three error messages as shown in the three attached screenshots:

When I run sudo apt update, it reports no errors, but does end by saying this: "4 packages can be upgraded. Run 'apt list --upgradable' to see them."

When I run sudo apt upgrade, it reports no errors, but does end by saying this: "The following packages have been kept back: libglib2.0-0 libglib2.0-bin libglib2.0-dev libglib2.0-dev-bin"

When I run sudo apt-get upgrade --with-new-pkgs for those four packages, here is the result:

main1@system1:~$ sudo apt-get upgrade --with-new-pkgs libglib2.0-0 libglib2.0-bin libglib2.0-dev libglib2.0-dev-binReading package lists... DoneBuilding dependency tree...

This may mean that you haverequested an impossible situation or if you are using the unstabledistribution that some required packages have not yet been createdor been moved out of Incoming.The following information may help to resolve the situation:The following packages have unmet dependencies: chrome-gnome-shell : Depends: gnome-shell but it is not installable gdm3 : Depends: gnome-shell (>= 3.37.90) but it is not installable gnome-shell-extension-appindicator : Depends: gnome-shell (>= 3.33) but it is not installable                                      Depends: gnome-shell (< 43~) but it is not installable gnome-shell-extension-desktop-icons-ng : Depends: gnome-shell (>= 3.38) but it is not installable gnome-shell-extension-prefs : Depends: gnome-shell (= 42.5-0ubuntu1pop1~1675984688~22.04~f574f54~dev) but it is not installable gnome-shell-extension-ubuntu-dock : Depends: gnome-shell (< 43) but it is not installable                                     Depends: gnome-shell (>= 40) but it is not installable ubuntu-desktop : Depends: gnome-shell but it is not installable ubuntu-desktop-minimal : Depends: gnome-shell but it is not installable ubuntu-session : Depends: gnome-shell (>= 3.37.91) but it is not installableE: Broken packages

But, chrome-gnome-shell, gnome-shell, ubuntu-desktop, etc., are all already installed and running just fine.

When I run Synaptic, it reports no broken packages.

Questions:

1. What are these Software Updater error messages shown in the screenshots above trying to tell me?
2. Are those Software Updater error messages related to the four libglib packages that are being held back?
3. Why does tyring to install those four libglib packages report that I have broken packages?
4. What should I be doing to fix whatever is wrong? (And, I do realize that one of the error messages above suggested using ppa-purge on some offending application, but I have no idea which application it is referring to.)

Thanks in advance for any help.

Update: Here is the output of sudo apt update:
