My Ubuntu has been telling me almost 3 weeks now to upgrade to Ubuntu 14.04, so yesterday I finally did it. But now I can't even log in. No password asking, no anything.. Can't get to the terminal, can`t do anything.

When I try to login I get only the usual purple background that says Ubuntu. Then it goes black. A white message box gives me a message that I have to manage by myself and what do I want to do (see the screenshot below). Well, I want it to work! I don't even know how to get to the terminal or what to write in it.

There is a known bug in Ubuntu 14.04 which prevents login if the user's home directory was encrypted and the user changed the password during upgradation. Is that the case with you?

You can review the option as in Comment #8 on the Launchpad. You can try signing into the terminal by pressing CTRL+ALT+F1 (to F6).

ITs because your lightdm is crashed. Do the following things

Press ALT+CTRL+F1

You will get tt1

Login as username = root

Password what you set for you system

Now enter the following lines

vim /etc/lightdm/lightdm.conf.d/50-unity-greeter.conf.dpkg-bak //an editor opens b4 u

Delete what is there and add the following lines

[SeatDefaults]

greeter-session=unity-greeter

user-session=ubuntu

greeter-show-manual-login=true

Also edit the following file

vim /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf

[SeatDefaults]

greeter-session=unity-greeter

user-session=ubuntu

greeter-show-manual-login=true

Now Restart the system using the following command

init 6 //Reboot system
