當我localectl show-locales在 Debian 上執行時，我看到

$ localectl list-locales
C.UTF-8
en_US.UTF-8

為什麼這個列表如此簡短？

包裹locales-all

要在 Debian 上安裝您需要添加的語言環境，

sudo apt install locales-all

然後你會得到一堆，

$ localectl list-locales | wc -l
151

包含

如果您只需要某些語言環境，dpkg-reconfigure locales請以 root 身份執行並選擇您想要的語言環境。

或者只是編輯/etc/locale.gen預設情況下有一長串註釋掉的語言環境。取消註釋您希望啟用的任何語言環境，然後locale-gen以 root 身份執行。
