I run Ubuntu 12.04, I can't set the locale to en_US.utf8. I set the LANG by configuring /etc/default/locale as described here.

$cat /etc/default/locale

LANG=en_US.utf8

$locale

LANG=

LANGUAGE=

LC_CTYPE="POSIX"

LC_NUMERIC="POSIX"

LC_TIME="POSIX"

LC_COLLATE="POSIX"

LC_MONETARY="POSIX"

LC_MESSAGES="POSIX"

LC_PAPER="POSIX"

LC_NAME="POSIX"

LC_ADDRESS="POSIX"

LC_TELEPHONE="POSIX"

LC_MEASUREMENT="POSIX"

LC_IDENTIFICATION="POSIX"

LC_ALL=POSIX

But it doesn't work, as you can see above. How do I set this LANG variable to en_US.utf8?

The reason I am asking is, when I run echo -e "x03bb", I get a unicode greek letter lambda symbol displayed correctly, but my issue is with emacs. In the emacs, I can't display unicode symbols, eg: C-x 8 RET 03bb outputs u03bb, instead of a greek letter lambda symbol. I thought the issue is with these locale settings, but I can't set them.

Edit:
I think the problem is fixed.

$su $USER -c 'env; echo ==; locale' | egrep '==|LANG'



LANG=en_US

LANGUAGE=en_US

==

LANG=en_US

LANGUAGE=en_US

The solution for me was, I was using mintty to ssh into Ubuntu 12.04
Server Edition, so I had to configure ~/.pam_environment and
~/.etc/ssh_config, and ~/bashrc. But my real issue with emacs was
not about this ubuntu configuration, so I have no idea what this
LANG variable configuration is used for or if I set it to correct values.

Edit 2:
Here are the steps I've taken to solve this, following the suggestions
of ansivirus from the #ubuntu irc channel:

Add this to ~/.bash_profile

export LANGUAGE="en"

export LANG="C"

export LC_MESSAGES="C"

Add this to ~/.pam_environment (so this must be problematic)

LANG=en_US

LANGUAGE=en_US

Add this to /etc/ssh/sshd_config

UsePAM yes

Comment out this in /etc/ssh/ssh_config

#   SendEnv LANG LC_*

Try to reinstall locales

apt-get install --reinstall locales
