By passing wrong input as following:
 sudo update-locale LANGUAGE = en_US.UTF-8
result is:
...
#LANGUAGE=en
=

This "equal" sign that was added makes system completely unusable(can't run sudo anymore):

bentzy@bentzy-nb:~$ sudo vim /etc/default/locale
sudo: pam_open_session: Bad item passed to pam_*_item()
sudo: policy plugin failed session initialization

Fixed it booting from installation disk and fixing corrupted /etc/default/locale
