ne peut pas mettre à jour à cause du manque d'espace sur / boot, mais échec d'apt-get purge
J'ai mis en place unattended-upgrades sur un serveur Ubuntu 16.04 que j'ai. Je l'ai vérifiée aujourd'hui et _/boot_ est saturé. _apt-get_ et autres réponses suggèrent de lancer _apt-get purge <old-kernels>_, mais cette commande échoue également pour moi. Je suppose que cela est dû à des paquets partiellement configurés?
Comment puis-je forcer _apt-get_ à supprimer les anciens paquets sur _/boot_? De même, existe-t-il un moyen de configurer _unattended-upgrades_ pour supprimer périodiquement les anciens packages de noyau non utilisés?
Voici la sortie de ma console lorsque j'essaie de mettre à jour et de purger les paquets

Succès! Il est intéressant de noter que _dpkg --purge_ a échoué spécifiquement sur les packages _4.4.0-89-generic_. Je ne sais pas trop pourquoi. Cela a fonctionné pour d'autres et a libéré l'espace avec succès. Après avoir exécuté _dpkg --purge_ sur quelques paquets, il me restait assez d’espace sur _/boot_.

_Maintenant, les commandes _apt-get -f install_ et _apt-get purge <package>_ suivantes aboutissent.
Poster une réponse à ma propre question basée sur un commentaire
La solution consiste à utiliser dpkg --purge pour supprimer les anciens packages du noyau. Plus précisément, les packages linux-image-x.x.xx-xxx-generic et linux-image-extra-x.x.xx-xxx-generic doivent être supprimés. dpkg échoue encore pour moi lorsque je ne spécifie que l'un d'entre eux. Aussi , notez que dpkg --purge échoue toujours pour certains des packages. Je pense que cela est dû à certains paquets à moitié configurés ou à moitié installés, bien que je n’aie pas vérifié.
Voici les commandes purge réussies que j'ai exécutées:
Sudo dpkg --purge linux-image-4.4.0-92-generic linux-image-extra-4.4.0-92-generic
Sudo dpkg --purge linux-image-4.4.0-96-generic linux-image-extra-4.4.0-96-generic
Sudo dpkg --purge linux-image-4.4.0-93-generic linux-image-extra-4.4.0-93-generic
Sudo dpkg --purge linux-image-4.4.0-97-generic linux-image-extra-4.4.0-97-generic
Par la suite, /root n’est rempli qu’à 51%, contre 100% d’origine.
# Original
user@Host:~$ df -h
Filesystem Size Used Avail Use% Mounted on
~~~ snip ~~~
/dev/sda1 472M 467M 0 100% /boot
# After dpkg --purge
user@Host:~$ df -h
Filesystem Size Used Avail Use% Mounted on
~~~ snip ~~~
/dev/sda1 472M 226M 222M 51% /boot
Maintenant, je peux réparer avec succès les installations cassées avec
apt-get -f install
