I have Ubuntu 16.10 installed on a Crypto-LUKS partition, and within that partition, there is an ecryptfs encrypted /home folder. My Ubuntu OS won't boot anymore for unknown reasons as stated yesterday. So I went and booted my computer from a Live CD of Ubuntu.

I can see the encrypted drive with a padlock symbol on it and when I click on it, it prompts me for the passphrase, I type it in and it unlocks the drive. After that, I went ahead and tried to run ecryptfs-recover-private on a Terminal to see if it can find the encrypted /home folder. But, after a while, it doesn't find the directory. Let's be clear here, I know the Login password, but have no idea what the recovery passphrase for ecryptfs is. Is there still a chance for me to recover the files?

Output of sudo ecryptfs-recover-private

INFO: Searching for encrypted private directories (this might take a while)...
find: ‘/run/user/999/gvfs’: Permission denied 
find: File system loop detected; ‘/sys/kernel/debug/pinctrl’ is part of the same file system loop as ‘/sys/kernel/debug’.

But I know that there is a private directory in /mnt/home/<user name>/, as I mounted the crypto_LUKS partition onto this directory using udisksctl, how did the program NOT find that? Did I do something wrong?

  • May I ask why you would want double encryption? – Android Dev Jan 24 '17 at 14:05
  • I think initially, I was thinking that some sensitive data (financial information) is stored there, so I might as well use 2 passphrases with identical length to encrypt that stuff. – user2213307 Jan 24 '17 at 14:15

    I found the answer by trial and error: essentially, I needed to do sudo chroot /mnt then run ecryptfs-recover-private. I was then prompted for the Login password and successfully gained access... – user2213307 Jan 24 '17 at 14:27
  • Please post that in the answer section then :) – Android Dev Jan 24 '17 at 18:48
