I don't have any programing background. So, I was upgrading the system via terminal, when it just started, i pressed suspend, instead of lock. The screen froze. I switched it off. And when restarting, it give a terminal like screen. Asking for Login and password. I used ecryptfs to check if my partition still exists. I entered my login name and password and the mount passphrase. It works and indicated that the partition is mounted and decrypted. So, I tried to do the same process using live CD. I get a response that my partition is recovered and mount. It asks for login credential, and it accepts it. But I face à problem with the mount passphrase wrapping. Can anyone please help me? Thanks

  • Do you want a Desktopenviroment back? As far as I understand, the system starts, but you're interface is missing. You can run this command, to see which version of ubunut is running: lsb_release -a. Please edit your question to give us this information too.

Try to update and upgrade

You're setup seems to be interrupted during a update. But since you have a terminal infront of you, cou can still fix everything. Just run these commands and pay attention to the qesions asked on your screen:

sudo -i # change user to root
apt update # get the newes information form the ubuntu repository servers
apt upgrade # installs the newer packages

I think, you will get some inforamtions during your the apt commands, espacially the last lines before you can enter something. I think they can helpo you too.

Test internetconnection

You can test your internetconnection with these two commands.

host security.archive.ubuntu.com
ping -c 8

From your infromation given in the comments, it seems your network is not working.

If you got a Lan-cable, use it. Else, try nmtui or other suggestions from here.

Then run a testcomand from above.

  • I followed these commands : $ sudo rm /var/lib/apt/lists/lock $ sudo rm /var/lib/dpkg/lock $ sudo rm /var/lib/dpkg/lock-frontend $ sudo dpkg --configure -à. Then I restarted. And chose the recovery mode. I found a new option to upstart the system. I chose it. It logged me in. I copied my files. And now I am upgrading the system, through the system update interface. Thanks a lot man for all the help. Mu ch appreciated

  • You must be carefull when you delete the lock-files, Be sure no apt or dpkg are running. I'm happy you managed to fix and upgrade your installation.
