Error: Unwrapping passphrase (Incorrect wrapping key)

I have the same problem.
I've been working with my encrypted home folder for about an year, and suddenly I cannot mount it.
I tried booting from live cd, and maybe all ecryptfs-* commands, and nothing didn't worked. It kept telling me its the wrong passphrase.
Please help us recover our precious home directory...

Do you still have the file $HOME/.ecryptfs/wrapped-passphrase?

If so, can you do:

ecryptfs-unwrap-passphrase $HOME/.ecryptfs/wrapped-passphrase

Thanks Dustin.

Still doesn't work:
root@ubuntu:/home/ubuntu# ecryptfs-unwrap-passphrase /media/14798a16-57e4-4bb4-9983-fd9e41d4521c/home/.ecryptfs/ohad/.ecryptfs/wrapped-passphrase
Passphrase:
Error: Unwrapping passphrase failed [-5]
Info: Check the system log for more information from libecryptfs

What is the output of:

ls -halF /media/14798a16-57e4-4bb4-9983-fd9e41d4521c/home/.ecryptfs/ohad/.ecryptfs/wrapped-passphrase
file /media/14798a16-57e4-4bb4-9983-fd9e41d4521c/home/.ecryptfs/ohad/.ecryptfs/wrapped-passphrase

Also, look for any ecryptfs messages toward the end of /var/log/syslog

Hi Dustin!
Thank you for helping out!! It's sincerely appreciated.

Why do I now get "command not found"?
According to Ubuntu's software central, it *is* installed, and I used it
like a week ago. What's its path, so I can be specific on the command line?

"
torben@torben-nettop:/$ ecrypt-unwrap-passphrase
/media/0f417b42-11a0-4539-9cae-e11ce3b289c3/home/.ecryptfs/torben/.ecryptfs/wrapped-passphrase

ecrypt-unwrap-passphrase: command not found
torben@torben-nettop:/$
"

If you're getting command-not-found, you need to:
 $ sudo apt-get install ecryptfs-utils

and from syslog:

ohad,

So the passphrase you're giving it when prompted is incorrect.

It's already installed (see below), but apparently not in the default path.
Can I just write "$ /path/to/ecryptfs/ ecrypt-unwrap-passphrase
/media/etc..." ?
--> What path should I use?

$ sudo apt-get install ecryptfs-utils
[...]
ecryptfs-utils is already the newest version.
ecryptfs-utils set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

If ecryptfs-unwrap-passphrase is not in your path, then yes, of
course, you much call it with its absolute path.

But still, it automatically mounted my home on every boot every day. One day it just stopped doing it.
And I'm pretty sure I remember the password, and I also saved the passphrases.

Do you have the long, random passphrase that you were told to record?

Yed I do.

So I am facing kind of similar issues after booting up and running 'aptitude upgrade' after a long while.

I tried this command:
ecryptfs-unwrap-passphrase $HOME/.ecryptfs/wrapped-passphrase

and entered my passphrase (which was a 32 character string which looked like base64 encoded) and got the exact same message mentioned by ohad in /var/log/syslog. Could this be an issue with the recent software upgrades?

I'm not currently on it but I experienced this on my laptop with a Debian Wheezy/Testing (after the freeze) installation and one day after having alternated between a hibernated and woken state for several days and upgrading in the my OS during this time. I noticed that chromium was "misbehaving" (I have a symlink of chromium's configuration folder pointing to ~/Private) such that Google searches would not show the text boxes properly so I rebooted and that's when I could not access anything in ~/Private. I'm pretty sure I know the correct password. I have a record accessible to me which tells me my pass phrase. I decided (a while back) to make my own password using ecryptfs-wrap-passphrase after some message with an auto-generated password (I wanted my own password).

Has anyone resolved this issue?
