gnome-remote-desktop and gnome-shell reported as "broken" on upgrading to 23.10

[Jos Geluk]

Upgrading to 23.10 fails because of an "unresolvable problem". I am cautioned to purge any PPA packages that I have installed. I have no such packages, only repositories. In /var/log/dist-upgrade/main.log, the packages gnome-remote-desktop and gnome-shell are being reported as "broken".

I did `sudo apt reinstall ubuntu-desktop` and then I was able to proceed with the upgrade.
