Updated stuff with Updatemanager problem

Question

I thought I needed to update stuff because of my computer randomly logging me out, So I saw that there was 1,418 updates so I installed them then after that I restarted the computer and I logged in and all that I saw was only my background picture of my desktop... Nothing else just the picture.

Follow these steps

• When you system opens press Ctrl+Alt+F1 to go to tty1 CLI Mode.

• Login with your credentials

• Execute these commands in series(one by one):

  sudo apt-get autoremove
  sudo apt-get autoclean
  sudo apt-get -f install
  sudo apt-get dist-upgrade
  

  If you get any error in any particular command, just mention it with the error message. All the commands should execute without any error.

• Now execute following command:

  sudo dpkg --configure -a
  sudo dpkg-reconfigure lightdm
  

  One list will open which will prompt to chose the display manger. Chose lightdm from the list and then ok. You'll need to press Tab to highlight Ok.

• Then restart your system by following command:

  sudo reboot
  

After reboot your system should work fine.. Reply if something goes wrong or for further assistance..
