安装的时候选的语言是en_US，结果现在的默认编码成了ANSI_X3.4-1968而不是UTF-8

我的enviroment是
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:
/usr/games"
LANGUAGE="en_US:en"
LC_ALL ="en_US.UTF-8"
LC_CTYPE=zh_CN.UTF-8
LANG=en_GB.UTF-8
GST_ID3_TAG_ENCODING=GBK

而我运行了sudo dpkg-reconfigure locales只是：
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "en_US:en",

are supported and installed on your system.

而没有让我设置

该怎么改成utf-8呀？ 另外我仍然想桌面是en_US的

locale 不对

1.编辑 /etc/belocs/locale-gen.conf
把PURGE改为yes
2.在/var/lib/locales/supported.d目录下设置你需要的locale
比如只保留 en zh local
其中en为: en_US.UTF-8 UTF-8
zh为: zh_CN.UTF-8 UTF-8
zh_CN.GBK GBK
zh_CN.GB2312 GB2312
local为: en_US.UTF-8 UTF-8
3. 运行locale-gen
sudo locale-gen

之后需要修改回来么？
