This question already has an answer here:

When i log in to my Ubuntu 12.04.4 LTS it takes me immediately back to my log in screen. This behavior began when I pressed the power button during installation of updates (to a new version of Ubuntu) somewhere around June or July of this year. If I type the wrong password it says "incorrect login". If I type the correct password, it goes black for a second then comes back to the log in page again. The log in page looks completely different than it used to under Ubuntu 12.04.4 LTS. When I press and then log in it just says incorrect login over and over again no matter what.

Press Ctrl-Alt-F1 in login screen to switch to fallback console. There, type

ping www.ya.ru

to check if you have Internet. If you do not, and do not know how to fix it, better reinstall. If yes, type

sudo apt-get install -f

to try autofixing updates. Then type

sudo do-release-upgrade

then, may be, you will have to flush your user prefrences.

mkdir ~/oldsettings
mv ~/.* oldsettings/
  • When I press Ctrl-Alt-F1 it takes me to that black & white login console that looks like a command shell that takes up the entire screen. Once their typing ping does nothing. It acts like I'm typing in my login information incorrectly. I think maybe I'm typing ping in the wrong place or not going to the screen you're trying to tell me to go to. Does that make sense? – E.J. Nov 3 '14 at 23:18
