第一步：编辑文件
代码：sudo gedit /var/lib/locales/supported.d/local
（这个文件是所有已经激活的区域语言的列表）
写入相关内容，比如写入如下内容：
zh_CN.UTF-8 UTF-8
zh_CN GB2312
zh_CN.GBK GBK
n_US.UTF-8 UTF-8
fr_FR ISO-8859-1
zh_CN.GB18030 GB18030
zh_CN.GBK GBK
n_US.UTF-8 UTF-8
fr_FR ISO-8859-1
zh_CN.GB18030 GB18030
第二步：生成相关的locales
代码：sudo locale-gen --purge
第三步：编辑文件
代码：sudo gedit /etc/default/locale
写入相关内容.比如,写入如下内容：
LANG="zh_CN.UTF-8"
LANGUAGE="zh_CN:zh"
LC_ALL="zh_CN.UTF-8"
LANGUAGE="zh_CN:zh"
LC_ALL="zh_CN.UTF-8"
第四步：重启电脑，终端中输入命令locale,看看命令是否报错,正常的结果如下：
代码：
~$ locale
LANG=zh_CN.UTF-8
LANGUAGE=zh_CN:en
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"

LC_IDENTIFICATION="zh_CN.UTF-8"
LC_ALL=zh_CN.UTF-8
LANG=zh_CN.UTF-8
LANGUAGE=zh_CN:en
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"
LC_COLLATE="zh_CN.UTF-8"
