My son kindly crashed my laptop and when I restarted it, cryptsetup did not accept my password (going into 60 minute delay). I cannot launch Ubuntu 18.04 that I have installed on my laptop SSD, but I can launch with a Live USB and unlock the laptop SSD using the Disks utility.

I see no way to mount the drive. I also tried to access the drive through command prompt and I get an error message, as shown below.

$ fdisk -l
fdisk: cannot open /dev/loop0: Permission denied
fdisk: cannot open /dev/loop1: Permission denied
fdisk: cannot open /dev/loop2: Permission denied
fdisk: cannot open /dev/loop3: Permission denied
fdisk: cannot open /dev/loop4: Permission denied
fdisk: cannot open /dev/loop5: Permission denied
fdisk: cannot open /dev/loop6: Permission denied
fdisk: cannot open /dev/nvme0n1: Permission denied
fdisk: cannot open /dev/sda: Permission denied

Then try to unlock it:

cryptsetup luksOpen /dev/nvme0n1 my_enc_hard

And get this message

Device /dev/nvme0n1 doesn't exist or access denied.

    Please add your error message to the question with [edit]. Take a look at https://milosophical.me/blog/2014/mounting-lukslvm-from-a-liveusb.html and https://askubuntu.com/questions/63594/mount-encrypted-volumes-from-command-line – K7AAY Aug 22 '19 at 22:33
  • I use this to see what drives I see:

    fdisk -l

    fdisk: cannot open /dev/loop0: Permission denied fdisk: cannot open /dev/loop1: Permission denied fdisk: cannot open /dev/loop2: Permission denied fdisk: cannot open /dev/loop3: Permission denied fdisk: cannot open /dev/loop4: Permission denied fdisk: cannot open /dev/loop5: Permission denied fdisk: cannot open /dev/loop6: Permission denied fdisk: cannot open /dev/nvme0n1: Permission denied fdisk: cannot open /dev/sda: Permission denied

  • Then try to unlcok it:

    cryptsetup luksOpen /dev/nvme0n1 my_enc_hard

    Device /dev/nvme0n1 doesn't exist or access denied.

    I don't understand what is the issue;

    When I use

    sudo cryptsetup luksOpen /dev/nvme0n1 my_enc_hard

    I am not prompted to enter my password.

  • I also don't understand why I can open the drive with Disks utility from USB, but I am not prompted to enter the password when I try cryptsetup luksOpen ... – Amir Memartoluie Aug 23 '19 at 01:10
