How to Fix "bash: warning: setlocale: LC_ALL: cannot change locale (en_US)"

Tested on Debian. Edit the default locale: ``` sudo vim /etc/default/locale ``` Add the following: ``` LANGUAGE=en_US.UTF-8 LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8 ``` Run these commands: ``` sudo locale-gen en_US.UTF-8 sudo dpkg-reconfigure locales ``` Note if you're connecting to a server the issue might be on either your machine or the server.
