I got warning setlocale LC_CTYPE when I ssh connect to vagrant centos 6
For CentOS or Amazon AMI Linux, add these lines to /etc/environment (create it, if it doesn't exist):
LANG=en_US.UTF-8LC_ALL=en_US.UTF-8To edit this file via SSH console, try
sudo nano /etc/environmentEdit
For Debian-related distributions (Ubuntu, etc.), you should check that /etc/default/locale is empty. That's the outcome of choosing None in dpkg-reconfigure locales which is suggested if users access via SSH (see Debian Wiki).
/etc/environment is deprecated since Debian Lenny (5.0).
In my case, on Slackware64 14.1 I got the error:
-bash: warning: setlocale: LC_ALL: cannot change locale (en_DK.UTF-8)It turned out to be missing glibc packages.
Installing the packages:
glibc-2.17-x86_64-11_slack14.1glibc-i18n-2.17-x86_64-11_slack14.1Solved the problem.
My /etc/profile.d/lang.sh contains:
export LANG=en_DK.UTF-8export LANGUAGE=en_DK.UTF-8export LC_ALL=en_DK.UTF-8export LC_COLLATE=CEnjoy.
