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:
- Make list of installed locales the same as all supported locales
- Generate locale files
- Show a list of all installed locales to verify installation
