Mise à jour Apt: problème de dissociation du fichier ... (30: système de fichiers en lecture seule)

J'ai essayé les solutions fournies par plusieurs autres questions sur AskUbuntu, mais aucune ne fonctionne comme décrit ci-dessous.

Sur Ubuntu 16.04.1 LTS, lorsque je lance

Sudo apt update

nous obtenons l'erreur suivante.

Tentative 1

~# mount -o remount,rw /
~# reboot

Résultat: Même erreur rencontrée après le redémarrage.

Tentative 2

~# Sudo fsck -Af
fsck from util-linux 2.27.1
~#reboot

Résultat: Même erreur rencontrée après le redémarrage.

Plus d'informations

~# dmesg | grep "EXT4-fs error"
~# mount -t ext4
/dev/vda1 on / type ext4 (ro,relatime,data=ordered)

Qu'est-ce qui se passe? Des idées?

J'ai eu le même problème sur Ubuntu 18.04.4.

Ensuite, j'ai vu que je ne pouvais rien exécuter lorsque terminal sur le répertoire home parce que le système de fichiers du répertoire home était read-only. Je pensais que le redémarrage résoudrait le problème, mais mon ordinateur est resté bloqué sur (initramfs) _ section lors du redémarrage. Mon répertoire personnel monté sous/dev/sda2 (Sudo fdisk -l pour voir ça).

Selon this réponse, j'ai tapé:

(initramfs) fsck /dev/sda2

puis:

(initramfs) reboot

Cela a résolu mon problème et je peux exécuter apt update et d'autres choses.

remarque: cette solution est une solution temporaire. Je vous ferai savoir si je trouve une solution permanente.

edit: J'ai vérifié que ma clé USB bootable ne contient pas d'erreurs. J'ai réalisé que l'USB amorçable contient beaucoup d'erreurs. Par conséquent, j'ai retourné le fichier Ubuntu .iso sur la clé USB et réinstallé Ubuntu. Cela a résolu mon problème. Je pense que la racine du problème était la clé USB bootable qui a beaucoup d'erreurs.

Vérifiez votre clé USB amorçable pour les erreurs si vous ne l'avez pas supprimée.
