How to fix a locale setting warning from Perl?

Question

When I run perl, I get the warning:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset         


        

Answer 1

Following the accepted answer:

LANG=C ssh hunter2.

LC_ALL=C ssh hunter2

on the client side did the trick for me.

Answer 2

As always, the devil is in the detail...

On Mac OS X v10.7.5 (Lion), to fix some Django error, in my ~/.bash_profile I've set:

export LANG=en_EN.UTF-8
export LC_COLLATE=$LANG
export LC_CTYPE=$LANG
export LC_MESSAGES=$LANG
export LC_MONETARY=$LANG
export LC_NUMERIC=$LANG
export LC_TIME=$LANG
export LC_ALL=$LANG

And in turn for a long time I got that warning when using Perl.

My bad! As I've realized much later, my system is en_US.UTF-8! I fixed it simply by changing from

export LANG=en_EN.UTF-8

to

export LANG=en_US.UTF-8

sudo nano /etc/locale.gen

Uncomment the locales you want to use (e.g. en_US.UTF-8 UTF-8):

Then run:

sudo /usr/sbin/locale-gen

I am now using this:

$ cat /etc/environment
...
LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8

Then log out of SSH session and log in again.

Answer 5

It is simple fix in Ubuntu. You have to generate the Locales from scratch, running the following commands from the command line:

sudo locale-gen en_US en_US.UTF-8
sudo dpkg-reconfigure locales

This should create the locales and then re-configure them.

Answer 6

If you use Mac OS X v10.10 (Yosemite) or above to connect in your server Linux, you can try these steps.

1. Keep your file /etc/ssh/sshd-config original

2. Put on your ~/.bash_profile

   export LANG="en_US"
   export LC_ALL=$LANG.UTF-8
   

3. Run

   dpkg-reconfigure locales
   

   And select "en_US.UTF-8"
