On 12.04 LTS x64, I changed my user password via the User Accnts tool. After that I was unable to login again with my new password since my home directory is encrypted and the above-described bug does not allow decryption of the home directory with the new login password.
The passphrase to decrypt the home directory is saved in a folder on my encrypted home directory.
Is there any way to recover this passphrase and unlock my home directory?
Do not have separate record of the decryption passphrase. I still have a functioning Guest Account to which I have access, but I am not clear whether I can somehow gain access to the files in my encrypted user home directory while logged in as Guest and without having the decrypt passphrase. Please advise asap.
