ssh默认覆盖LC区域变量。看到/etc/ssh/sshd_config:

AcceptEnv LANG LC_*

也许你需要在本地shell中设置这些变量。

尝试重新安装:

localess apt-get install --reinstall locales

更多信息请参见如何更改默认区域设置

对于任何从iTerm2连接到DigitalOcean或其他云托管提供商的人。在macOS v10.13 (High Sierra)上运行app，在一些命令上得到这个错误:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LC_CTYPE = "UTF-8",
    LANG = "en_US.UTF-8"
  are supported and installed on your system.
perl: warning: Falling back to a fallback locale ("en_US.UTF-8").

这为我解决了问题:

这通常意味着您还没有正确地在Linux机器上设置区域设置。

在Debian或Ubuntu上，这意味着你需要去做

$ sudo locale-gen
$ sudo dpkg-reconfigure locales

另参见man locale-gen。

每当我在最新的Kali Linux版本上运行Perl脚本(比如enum4linux)时，都会遇到这个问题。

kali@kali:~$ lsb_release -a
No LSB modules are available.
Distributor ID:    Kali

例如,

kali@kali:~$ enum4linux

请看给出的警告信息。

perl: warning: Falling back to a fallback locale ("en_US.UTF-8").

另外，注意LC_ALL = (unset)

解决办法很简单。你所要做的就是设置它。

export LC_ALL=en_US.UTF-8

例如,

kali@kali:~$ export LC_ALL=en_US.UTF-8
kali@kali:~$

问题解决了

kali@kali:~$ enum4linux

对于永久解决方案，您可能希望将其添加到.bashrc文件中。

您需要在/etc/default/locale中适当地配置语言环境、注销、登录，然后运行常规命令

root@host:~# echo -e 'LANG=en_US.UTF-8\nLC_ALL=en_US.UTF-8' > /etc/default/locale
root@host:~# exit
local-user@local:~$ ssh root@host
root@host:~# locale-gen en_US.UTF-8
root@host:~# dpkg-reconfigure locales
