Ubuntu not booting (after fsck in GUI then probable power loss)

Jakub

I would appreciate any help with my problem. At this point I would be happy if I can access my data on sda3 and reinstall OS.

My Ubuntu is not booting correctly after:

  1. fsck run in GUI
  2. fsck finished very quickly, I tried power off
  3. unusual long time, I went to sleep
  4. in the morning probably power cable was disconnected
  5. Ubuntu not booting, hangs on "loading initial ramdisk..."

My sda3 was LUKS crypted partition.

Then:

  1. recovery mode - the same ramdisk message
  2. liveusb - many attemps with fsck, smartools, boot-repair
  3. boot-repair was doing things but with no effects
  4. sda3 was decrypted and now is LVM2
  5. after #4 "default repair" button in boot-repair disappeared and never came back
  6. can't mount /dev/sda3: unknown filesystem type 'LVM2_member'
  7. can mount /dev/mapper/ubuntu--vg-root
  8. couldn't chroot anywhere: failed to run command /bin/bash: no such file or directory
  9. tried grub repairs: grub-install failed to get canonical path of /cow
  10. many fsck attepts: Ubuntu is now booting straight to initramfs
  11. fsck from initramfs level: 15 minutes of processing, no effect

boot-repair log:

    boot-repair-4ppa130                                              [20210911_1022]

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would not act on the boot.

As I mentioned - any way that will allow me to backup the data will be enough.

Nu ați spus ce versiune de Ubuntu încercați să reparați, dar grub 2.00 implică că este de la sfârșitul lui 2012 sau începutul lui 2013 și doar versiunile acceptate ale Ubuntu sunt la subiect aici. Consultați https://askubuntu.com/help/on-topic unde veți observa doar versiunile acceptate de Ubuntu și aromele sunt la subiect pentru acest site.

Am întrebat despre sistemul instalat, nu despre sistemul *live* (grub 2.04 este versiunea folosită de 20.04)

Pot verifica versiunea de la nivelul terminalului liveusb?

Fișierul `/etc/os-release` ar trebui să conțină acel detaliu; cu toate acestea, acesta va arăta și sistemul dvs. *live*; deci ajustați pentru sistemul dvs. instalat „montat” (și criptarea dacă este sda3)

de la nivelul initramfs (fără liveusb): VERSION=18.04.5 LTS (Bionic Beaver). Și de la nivelul meniului de pornire în timpul pornirii: 4.15.0-154-generic este disponibil la alegere.

întrebarea această in alte limbi:

Postează un răspuns

Majoritatea oamenilor nu înțeleg că a pune multe întrebări deblochează învățarea și îmbunătățește legătura interpersonală. În studiile lui Alison, de exemplu, deși oamenii își puteau aminti cu exactitate câte întrebări au fost puse în conversațiile lor, ei nu au intuit legătura dintre întrebări și apreciere. În patru studii, în care participanții au fost implicați în conversații ei înșiși sau au citit transcrieri ale conversațiilor altora, oamenii au avut tendința să nu realizeze că întrebarea ar influența – sau ar fi influențat – nivelul de prietenie dintre conversatori.
