I am on Ubuntu 12.10 with one user using encrypted home.
A while back I have changed by user password and then forgot it.
I then made a backup of my files using Dustin's help to an external drive. I was about to delete my system and do a fresh install when I realized that there is a recovery option in which I can reset my user password. Using How do I reset a lost administrative password? I have set a new password for my user.
After rebooting I can log-in in Unity using my new password but I am thrown back to the Unity screen immediately. (No message about false password)
Using the terminal I can log in using the new user-password.
How can I re-enable my machine to decrypt my ecrypfs encrypted home with the unwrapped passphrase I know?
