Changing system language from Italian to English on Debian 9 DE, without affecting keyboard settings

Question

I need to change the language of my PC, which is running Debian 9 Stretch with xcef4 DE.

Browsing on the official Debian website, I tried to follow what the website suggested, by running from the terminal:

1. env | grep LANG

   and getting the following information about the language and the reference country set by default on the PC LANG=it_IT.utf8

2. export LANG=en_IT.UTF-8

   in order to set the English language and mantain the country settings like keyboard and all the other stuff.

Anyway, no results got, because the language did not change!

Can you help me to set the English language as the default language without change the keyboard settings.

Answer 1

Just use:

dpkg-reconfigure locales

And select the default language (from the list of locales generated on the first screen (you could select several)) in the second screen.
