Puppet supprime des paquets lors de l'installation de "lsscsi".

Nous voulions installer le paquet "lsscsi" sur tous nos serveurs Linux et construire un manifeste pour celui-ci :

# pack_lsscsi.pp

class common::pack_lsscsi  {

        case $operatingsystem {
                RedHat, CentOS, Debian: {
                        package { 'lsscsi':
                                ensure  => 'installed',
                        }
                }
        }
}

Le paquet "lsscsi" n'a que "libc6" comme dépendance - donc pas de problème du tout. Tout s'est bien passé sur nos serveurs Red Hat et CentOS, mais certains systèmes Debian sont devenus fous. Puppet a supprimé entre 10 et 180 paquets, comme sur celui-ci :

Une idée de comment cela pourrait se produire ?
