[linux] BadValue Invalid or no user locale set. Please ensure LANG and/or LC_* environment variables are set correctly

When I run mongo, I get the warning:

Failed global initialization: BadValue Invalid or no user locale set. Please ensure LANG and/or LC_* environment variables are set correctly.

adding the following lines to my /etc/environment file worked

LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8

you can use the below command on terminal

export LC_ALL=C

vim /etc/default/locale

add to it:

LC_ALL="en_US.UTF-8"

Amazon Linux AMI

Permanent solution for ohmyzsh:

$ vim ~/.zshrc

Write there below:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8

Update changes in current shell by: $ source ~/.zshrc

you have to add the missing local lang helper: for me the missing ones where de_LU de_LU.UTF-8 . Mongo 2.6.4 worked wihtout mongo 2.6.5 throw an error on this
