在我的 Debian Wheezy VPS 上，切换用户时，我不断收到与区域设置和区域设置更改相关的错误，例如：
-su: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
当执行几乎所有与安装相关的操作时（apt-get 和 dpkg）：
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
我已经研究过它，并发现了一些关于此类错误的问题。
的输出locale -a是：
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
我还尝试安装 locales 包，但它也不起作用，例如locale-gen，没有改变任何东西。
编辑：输出strace locale -a如下（一大堆文本，请注意）

答案1
在我看来，文件丢失了。每种数据可以位于六个文件之一中，但不存在。
我没有 Debian 来检查，但使用 openSUSE 我有例如文件/usr/lib/locale/en_US/LC_CTYPE及其所属的包是glibc-locale。
可能包名与Debian相同。您应该（重新）安装它。
