In the menus at the login screen, you should be able to find an option to use fail safe gnome. If you manage to login that way, then open a terminal and enter


sudo apt-get install --reinstall libkrb53


If you can't log in using fail safe gnome, then reboot and choose recovery mode at startup. You should reach a console where you can enter the command above.
