Debian の無効なロケール

Debian Wheezy VPSでユーザーを切り替えると、次のロケールとロケールの変更に関連するエラーが発生し続けます。

-su: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

ほとんどすべてのインストール関連タスク（apt-getとdpkg）を実行する場合：

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = "en_US.UTF-8",
    LANG = "en_US.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
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

私はそれを調べたところ、この種のエラーに関連するいくつかの問題が見つかりました。

出力はlocale -a次のとおりです

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory
C
C.UTF-8
POSIX

また、ロケールパッケージをインストールしようとしましたが、うまくいきませんでした。つまり、locale-gen何も変更されていません。

編集する：出力はstrace locale -a次のとおりです（テキストが多いので注意してください）。

編集3：すみません、これはいいえ繰り返します。あなたが言ったように、いくつかの質問を見ましたが、あなたが指定した重複した回答を含むどんな回答も役に立ったか、問題を解決できませんでした。重複のように見えるかもしれませんし、理論的にはそうです。しかし、私の質問が解決されていないので、以前の質問を再度尋ねることは、新しい質問を尋ねるよりも問題を解決するのに役立つとは思わない。
