I changed my ubuntu user password using:
$ sudo passwd
now when I reboot and login using the new password, following warning is displayed:
Signature not found in user keyring
perhaps try the interactive 'ecrypt-mount-private'
Also
$ ls command
shows only these 2 dir: Access-your-private-data.desktop
and README.txt
I tried to start the graphical interface using:
$ startx
but recieved the following error:
timeout in accessing locking authority file /home/my_username(aman)/.Xauthority
I remember my old and new passwords but forgot the passphrase, so retrieved it using:
$ ecryptfs-unwrap-passphrase /home/aman/.ecryptfs/wrapped-passphrase
After this I'm not able to make out how to proceed and login to my home foler in graphical interface.
