сбросить языковой стандарт в debian под Squeeze

У меня проблемы с локалью в debian. Я много чего пробовал, но мне это ни к чему:

locale -a

locale: Cannot set LC_CTYPE to default locale: No such file or directory
C
POSIX
en_US.utf8

Я безуспешно пытаюсь установить en_US.utf8:

dpkg-reconfigure locales -plow
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = "en_US",
    LC_ALL = (unset),
    LC_CTYPE = "UTF-8",
    LANG = (unset)
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

После перезагрузки я пытаюсь использовать Perl-скрипт:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = "en_US",

    LC_CTYPE = "UTF-8",

Вот мой файл конфигурации / etc / default / locale:

cat /etc/default/locale 
LANG=en_US.UTF-8
LANGUAGE=en_US

Есть идеи решить эту (глупую) проблему?

Спасибо
