`processing triggers` while removing `gnome-shell` exposes slight bug related to `gschema.override`,

Hi,

I like the desktop very much, very nice job

I was installing gnome-shell and related framework files from Ubuntu 21.10 and noticed these bugs during processing triggers, I wanted to report them so you are aware:

❯ sudo apt remove gnome-shell gnome-shell-extension-desktop-icons-ng gnome-shell-extension-desktop-icons-ng gnome-shell-extension-prefs gnome-shell-extension-appindicator gnome-shell-common chrome-gnome-shell yaru-theme-gnome-shell

  gir1.2-gweather-3.0 gir1.2-mutter-8 gir1.2-rsvg-2.0 gstreamer1.0-pipewire
