Установка locales Debian/Ubuntu

Если вам достался сервер, у которого, не установлена русская локаль,
и он временами сыплет подобными предупреждениями.

Для ubuntu:

...
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LANG = "ru_RU.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory

Можно просто установить эту грешную локаль.
