package console-setup-linux 1.108ubuntu15.3 failed to install/upgrade: tentative de remplacement de « /lib/systemd/system/console-setup.service », qui appartient aussi au paquet keyboard-configuration 1.108ubuntu15.3

possibles causes: download of
-dosbox
-ginkgocadx
-virtualbox (from ubuntu repository) with utilities for file exchange between it and host: two libs, for mounting disk images.....
I think it was libguestfs-tools which generated a curious message in synaptik, about 3 packages (suppressed?)
virtualBox worked wrong also....

I just desinstalled dosbox when THIS bug appeared
