I installed Ubuntu and encrypted the home folder. Then I forgot the login password and tried to change it:
from the recovery mode, I've selected the root shell and at the prompt I entered:
mount -rw -o remount /
passwd username
init 2
during the init 2 command the power cut off and the computer shut down. After restart I couldn’t login at all. Then I remembered the login password and tried to set it:
from the recovery mode,at the root shell prompt I entered:
mount -rw -o remount /
passwd username
Restore the old password
reboot
Now I cannot login in the system any more.
I attached the drive with the encrypted home folder to an Ubuntu system and navigated to the home folder. This is the folder tree structure of it:
home/adrian/cache/wallpaper/photo
...................../Access-your-Private-Data.desktop (Note:it’s a text file with the content:
..............................................................................[Desktop Entry]
..............................................................................._Name=Access Your Private Data
..............................................................................._GenericName=Access Your Private Data
...............................................................................Exec=/usr/bin/ecryptfs-mount-private
...............................................................................Terminal=true
...............................................................................Type=Application
...............................................................................Categories=System;Security;
...............................................................................X-Ubuntu-Gettext-Domain=ecryptfs-utils)
....................../ReadMe.txt (Note:it’s a text file with the content:
.............................THIS DIRECTORY HAS BEEN UNMOUNTED TO PROTECT YOUR DATA.
..............................From the graphical desktop, click on:"Access Your Private Data"
.............................or from the command line, run: ecryptfs-mount-private)
......................./.ecryptfs (Note: the file contains a broken link:
it points to "/home/.ecryptfs/-adrian/.ecryptfs" the folder name “adrian” has been replaced with “-adrian”)
......................./.Private (Note: the file contains a broken link: it points to "/home/.ecryptfs/-adrian/.Private" the folder name “adrian” has been replaced with “-adrian”)
home/ecryptfs/adrian/.ecryptfs/auto-mount
..................................................../auto-umount
..................................................../Private.mnt
..................................................../Private.sig
................................................... /wrapped-passphrase
..................................................../.wrapped-passphrase-recorded
...................................../.Private (Note: the folder contains both folders and files with links that point to the folders- some links are broken they point to nonexistent folders: folders’ names have been corrupted again)
The followings are copied from a terminal window and from the “syslog” file:

The login passphrase is the right one and I used it to log into the system.
Does anyone know what to do next?
Could I use R-linux to search for the previous versions of the files that are now corrupted and try to replace them with the original ones?
Thanks for help,
andrew
