原本的 OB2D-XFCE-Server-2017 訊息是顯示中文的，但因個人使用習慣，所以移除了 X-Window，使用 SSH Client 遠端登入後，顯示訊息是中文的，就有些不太習慣。
# cp /etc/default/locale /etc/default/locale.$(date +%F)
# sed -i ‘s/zh_TW/en_US/’ /etc/default/locale
# sed -i ‘s/zh/en/’ /etc/default/locale
# locale-gen en_US.UTF-8
Generating locales (this might take a while)…
zh_TW.UTF-8… done
Generation complete.
但執行 locale 會出現警告提示的訊息
