Debians, I just installed Debian Buster with encrypted LVM.
In my fstab file, I have: # <file system> <mount point> <type> <options> <dump> <pass> /dev/mapper/try02--vg-root / ext4 errors=remount-ro 0 1 I can't figure out what device I should pass to cryptsetup to avoid the below error: $ cryptsetup -v luksAddKey /dev/mapper/try02--vg-root /etc/keys/root.key --key-slot=1 Device /dev/mapper/try02--vg-root doesn't exist or access denied. Command failed with code -4 (wrong device or file specified). How can I know what device cryptsetupt will accept? -- John Doe
