[Bug 2046859] [NEW] Upgrade to Mantic fails "Broken update-manager:amd64 Depends on gnome-shell:amd64"

[Roland]

Public bug reported:

This is a new machine, installed Lunar from scratch in about June. No
PPAs, first dist upgrade to Mantic.

I'm not able to make much sense of the gnome-shell error in
/var/log/dist-upgrade/apt.log
