I had a Ubuntu 11.10 and I upgraded it to 12.04.
At the installation it automatically created my home as "crypted" and gave me a message at the first login, I don't remember what I did at that moment.
Now my Hard Disk has big hardware issue and Ubuntu doesn't boot anymore.
I attached that primary Hard Disk as secondary hard disk, I was trying to mount it to recover some data.
When I mount /home I see my home empty and it says it's crypted.
The only thing I know is my username password.
Have I lost the data on the crypted home?
(I just wonder when linux was booting, where did it find the key to decrypt my homedir, maybe is somewhere in /etc and accessible with the root user?)
