Vagrantfile. Set locale for ssh agent

Question

I have a problem described here

This problem appears because host machine put locale to guest via ssh.

What is the proper way to solve this?

How I can force vagrant ssh to do this:

LC_ALL=en_US.UTF-8 vagrant ssh

each time?

I propose override host locale in Vagrantfile

Vagrant.configure(2) do |config|

  config.vm.box = "ubuntu/vivid64"

  ENV['LC_ALL']="en_US.UTF-8"

end

The change is not visible outside Vagrant (host env variables remains unchanged)

Please add some explanation to your answer. Code-only answers are generally considered to be of low quality – Tristan Jan 04 '16 at 01:41
I guess it works. but there is a question: Can the `ENV['LC_ALL']="en_US.UTF-8"` eventually change something on the host machine? – kharandziuk Jan 04 '16 at 09:58

My host remains unchanged, so I think the change is local only (BTW, I simplified my answer a little) – michaldo Jan 04 '16 at 20:07

I had the same problem on OSX (the solution is similar for Linux) when connecting to my Vagrant Ubuntu boxes.

I simply "solved" it by editing /etc/ssh_config (or /etc/ssh/ssh_config on Linux) and commenting the following line:

# SendEnv LANG LC_*

This basically stops ssh from sending the LANG and LC_ALL (all LC_ variables) to the remote host, resulting in using the default on the box. In this case en_US.UTF-8.

Obviously this will cause your remote connections to always use the default locale which may not be what you want.

I believe that you can also set the ssh preferences per host but never did so. I you are interested into that, it might be worth looking.

My answer: I just add a line to my ansible playbook. But it isn't an answer in terms of only Vagrant

- name: set locale
  lineinfile: dest=/etc/default/locale line="LC_ALL=C"

LC_ALL=en_US.UTF-8
LC_CTYPE=en_US.UTF-8

add these lines to ~/.bash_profile of VM, and restart VM via vagrant

Expanding on Havok's answer, you can make the VM provisioning ensure that a locale (en_US.UTF-8 below) is created, and used whenever you SSH into the VM (by running the necessary shell commands for configuring locales). In the Vagrantfile:

config.vm.provision "shell", inline: <<-EOF
  apt-get update
  apt-get install -y locales  # install locales support
  echo 'en_US.UTF-8 UTF-8' >> /etc/locale.gen
  locale-gen  # enable locales in `/etc/locale.gen`
  update-locale LANG=en_US.UTF-8  # setup default VM locale
  sed -i -E 's/^(\s*AcceptEnv\b)/#\1/' /etc/ssh/sshd_config  # avoid SSH overriding it
EOF

The proper way is to configure the ssh daemon in the virtual machine to do not accept this environment variables.

Modify in your development environment the file /etc/ssh/sshd_config and comment the AcceptEnv line like this:

$ cat /etc/ssh/sshd_config | grep AcceptEnv
# AcceptEnv LANG LC_*

If you're using Docker as provider you can put in your Dockerfile:

sed -i 's/AcceptEnv/# AcceptEnv/' /etc/ssh/sshd_config

You need to generate and set the default locale too. You can do that with:

# Set the locale
ENV LANG en_US.UTF-8
RUN locale-gen en_US.UTF-8 && update-locale LANG=en_US.UTF-8
