Est-il utile de purger un paquet de noyau au lieu de le supprimer ? Je pose cette question parce que la suppression automatique des paquets ne purge pas tous les paquets qu'elle supprime. (J'ai configuré cette suppression automatique dans /etc/apt/apt.conf.d/50unattended-upgrades et on dit qu'elle est équivalente à apt-get autoremve ) Au moins dpkg-query -L pour un tel paquet donne
Package 'linux-image-4.2.0-21-generic' does not contain any files (!)ce qui suggère qu'il n'y a pas de fichiers de configuration qui traînent. dpkg-query indique l'état deinstall ok config-files para linux-image-4.2.0-21-generic . Pour le paquet d'en-têtes correspondant linux-headers-4.2.0-21-generic , dpkg-query indique l'état not-installed et pour linux-headers-4.2.0-21 il n'y a pas de correspondance après l'opération de suppression automatique.
Pour ce qu'il vaut, voici un extrait de /var/log/unattended-upgrades/unattended-upgrades-dpkg.log :
