Install all locales

Installing all locales available on your system is surprisingly easy and can be done in three commands.

Open Terminal, then run the following:

sudo cp /usr/share/i18n/SUPPORTED /var/lib/locales/supported.d/local
sudo locale-gen
locale -a

Here’s what’s happening:

1. Make list of installed locales the same as all supported locales
2. Generate locale files
3. Show a list of all installed locales to verify installation
