Bonsoir !
Depuis quelques heures, mon disque s’est bloqué en lecture seule pendant une mise à jour via apt-get. La màj s’est arrêté brutalement (pas de coupure du système, de choc physique ou d’interruption du processus) depuis impossible d’accéder au disque en écriture. Il s’agit d’un disque SSD (je sais pas si ça change quelque chose. C’est le seul disque installé sur mon ordinateur et il est partitionné en / sur sda1, swap et /home sur sda2 (respectivement sda5 et 6), et l’ensemble du disque est inaccessible en écriture. Impossible donc de modifier le moindre fichier sur l’ordinateur… Par ailleurs le système fonctionne, mais je ne l’ai pas redémarré (dans le doute). J’ai fouillé un peu sur d’autres forum, ça n’a pas l’air d’être une erreur nouvelle, mais aucune des solutions proposées n’a marché chez moi…
Voilà les différents messages d’erreur que j’ai :
pour apt-get :
# apt-get install -f
W: Verrou non utilisé pour le fichier /var/lib/dpkg/lock en lecture seule
E: dpkg a été interrompu. Il est nécessaire d'utiliser « dpkg --configure -a » pour corriger le problème.
pour dpkg :
# dpkg --configure -a
dpkg: erreur: impossible d'accéder au répertoire administratif de dpkg: Système de fichiers accessible en lecture seulement
Du coup j’ai essayé de remonter le disque :
# mount -o remount,rw /
mount: impossible de remonter /dev/sda1 en lecture/écriture, est protégé en écriture
Voilà le résultat de dmesg :
# dmesg | grep sda
