Debian/Ubuntu 安装后并不一定提供了完整的语言支持，因此需要手动安装：

locale-gen en_US.UTF-8
export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales

thanks man

Thank you

It works ! thanks.

thanks

Since I do not have administrator rights, it will be "Permission denied" when I try to run locale-gen en_US.UTF-8.
I add these three lines to my shell and it works!
Thanks!!!

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
