After new Update, I'm getting error when I try to unlock my disk:

Warning: Failed to connect to lvmetad. Falling back to device scanning.
Volume group "ubuntu-vg" not found
Cannot process volume group ubuntu-vg
Please unlock disk sda3_crypt HERE I HIT PASSWORD

cryptsetup: cryptsetup failed, bad password or options?

After long search on forums, I supposed it's problem with keyboard layout, probably when I installed ubuntu I wrote password with UK layout and now after Update, layout was changed to US and I don't know how can I change to UK, maybe there are some commands in GRUB2.

  • When you say English layout do you mean UK layout? If so, there's only one major difference from the US layout, the @ and the ' sign are reversed. – To Do Jul 12 '19 at 16:33
  • @ToDo if it so, can I reinstall ubuntu again from scratch if disk is encrypted ? – Radeanu Vasile Jul 12 '19 at 16:40
  • You can, but you'll loose the contents of the encrypted partition if you are not cautious (!). – Tomáš Pospíšek Jul 12 '19 at 19:18
  • Also, if your /boot partition is not encrypted, then you should be able to change your keyboard layout from the grub CLI. See here for a starter: https://askubuntu.com/questions/751259/how-to-change-grub-command-line-grub-shell-keyboard-layout – Tomáš Pospíšek Jul 12 '19 at 19:19

I had similar issue wit a cached keyboard kmap.gz. My solution was:

  • load Ubuntu live from USB: I loaded Ubuntu 19, but 18.04 will work too
  • start Ubuntu disks
  • you will see the encrypted disk.
  • select it
  • in the settings menu, there is an option to change the key
  • click it
  • you will be asked for the current password and for type two times the new password

That's all. Reboot and use the new password.

Advice: use a digits combination always in a view to avoid such issues.
