How to install other region?

Solution 1:

First reinstall locale package:

sudo apt --reinstall install locales

Open this file:

sudo nano /etc/locale.gen

Find this line: # de_DE.UTF-8 UTF-8, uncomment it so it's now: de_DE.UTF-8 UTF-8. Save the file and run:

sudo locale-gen

see if you have German now.

Solution 2:

If you want German region formats, I think this is a way:

  1. Switch to German language, which will generate a few German locales.
  2. Switch back to English language.
  3. Now you should find some German region options.
