Intento 1

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

Resultado:Se encontró el mismo error después del reinicio.

Intento 2

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

Resultado:Se encontró el mismo error después del reinicio.

Más información

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

¿Lo que está sucediendo? ¿Algunas ideas?

Answer 1

Tuve el mismo problema en Ubuntu 18.04.4.

Luego, vi que no puedo ejecutar nada cuando estoy terminalen homeel directorio porque homeel sistema de archivos del directorio era read-only. Pensé que reiniciar resolvería el problema pero mi computadora se atascó en (initramfs) _la sección durante el reinicio. Mi directorio de inicio está montado como /dev/sda2 ( sudo fdisk -lpara ver eso).

De acuerdo aesterespuesta que escribí:

(initramfs) fsck /dev/sda2

entonces:

(initramfs) reboot

Esto resolvió mi problema y puedo ejecutar apt updatey otras cosas.

nota:esta solución es una solución temporal. Te haré saber si encuentro una solución permanente.

editar:He encontrado la solución. El problema ocurre si su disco tiene muchos archivos bad sectors. Tienes que ignorar estos sectores defectuosos en el disco.
