ubuntu无法安装en_us.utf-8提示无法找到文件或目录

问题描述：

1.运行: sudo locale-gen en_us.utf-8  或 en_us

提示：

 en_US.ISO-8859-1...failed to set locale!
[error] cannot open locale definition file `en_GB': No such file or directory
 done
  en_US.ISO-8859-15...failed to set locale!
[error] cannot open locale definition file `en_GB': No such file or directory
 done
  en_US.UTF-8...failed to set locale!
[error] cannot open locale definition file `en_GB': No such file or directory

2. 运行locale -a，显示系统中没有en_us.utf8字符集

    输出：

        C
        C.UTF-8

        POSIX
        zh_CN.utf8

3.运行dpkg-reconfigure locales 尝试安装en_us.utf-8也不成功

解决：

        卸载locales和语言包，重新安装，再执行locale-gen

sudo apt-get purge locales
sudo apt-get purge language-pack-en

sudo apt-get install locales
sudo apt-get install language-pack-en

sudo locale-gen en_us.utf-8

安装中文语言包，sudo apt install language-pack-hans 即可安装zh_cn.utf8

再次执行：locale -a

:~$ locale -a
