Package: gnome-core Version: 1:42+3 I believe caribou is a genuine mistake in dependencies (remove one that is no longer part of them).
https://wiki.gnome.org/Projects/Caribou states "Caribou is not under active development anymore." and "The GNOME Shell onscreen keyboard does not use Caribou anymore.". Performing "sudo dpkg -r --force-depends caribou" on an updated and upgraded sid installation with the gnome-core metapackage installed does not appear to break anything in Settings or any on screen keyboard functionality. I propose that caribou be removed from the dependency list of gnome-core.
