Русская локаль Ubuntu 12

Устанавливаем русскую локаль в Ubuntu из консоли:

locale-gen ru_RU.UTF-8

В /etc/default/locale пишем:

LANG="ru_RU.UTF-8"
LANGUAGE="ru_RU:en"
LC_NUMERIC="ru_RU.UTF-8"
LC_TIME="ru_RU.UTF-8"
LC_MONETARY="ru_RU.UTF-8"
LC_PAPER="ru_RU.UTF-8"
LC_IDENTIFICATION="ru_RU.UTF-8"
LC_NAME="ru_RU.UTF-8"
LC_ADDRESS="ru_RU.UTF-8"
LC_TELEPHONE="ru_RU.UTF-8"
LC_MEASUREMENT="ru_RU.UTF-8"

затем команда

sudo reboot

Если не помогло то делаем следующее
check which locales are supported :

less /usr/share/i18n/SUPPORTED

Add locale to list of generated

echo ru_RU.UTF-8 >> /var/lib/locales/supported.d/local

или вручную пишем в /var/lib/locales/supported.d/local

en_US ISO-8859-1
en_US.UTF-8 UTF-8
ru_RU.UTF-8 UTF-8
ru_RU ISO-8859-5

Regenerate list (it will invoke locale-gen…)

sudo dpkg-reconfigure locales
