Ubuntu encrypted home folder got corrupted

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: adi@adi-1:/$ sudo ecryptfs-mount-private /media/adi/d2bc773c-93e3-43e2-b1bc-e2d2430030cb/home/.ecryptfs/adrian/.Private [sudo] password for adi: ERROR: Encrypted private directory is not setup properly adi@adi-1:/$ sudo ecryptfs-recover-private /media/adi/d2bc773c-93e3-43e2-b1bc-e2d2430030cb/home/adrian/.Private INFO: Searching for encrypted private directories (this might take a while)... find: ‘/run/user/1000/doc’: Permission denied find: ‘/run/user/1000/gvfs’: Permission denied adi@adi-1:/$ sudo umount /run/user/1000/gvfs adi@adi-1:/$ sudo umount /run/user/1000/doc adi@adi-1:/$ sudo ecryptfs-recover-private /media/adi/d2bc773c-93e3-43e2-b1bc-e2d2430030cb/home/adrian/.Private INFO: Searching for encrypted private directories (this might take a while)...

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
