manpath: can't set the locale; make sure $LC_* and $LANG are correct

  • 772

When I ssh into an EC2 instance running Ubuntu 18.04, I get this error:

manpath: can't set the locale; make sure $LC_* and $LANG are correct

I tried this but this didn't fix it:

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

  en_US.UTF-8... done

    LC_TERMINAL = "iTerm2",
    LANG = "C.UTF-8"
    are supported and installed on your system.

  1. Another option is to disable sending LC_* environment variables. Refer to https://stackoverflow.com/questions/29609371/how-do-not-pass-locale-through-ssh , these steps fits for MacOS ssh client :

    sudo vi /etc/ssh/ssh_config

    Find these settings:

    Host *
      SendEnv LANG LC_*

    Change it to :

    Host *
#      SendEnv LANG LC_*

    Save the file, then try connecting again.

  2. Thanks to Gunnar Hjalmarsson I'm able to use this workaround:

    unset LC_CTYPE in ~/.profile

  3. I don't have enough reputation to comment, but I want to build on the YudhiWidyatama answer.

    Host * !host_to_omit1 !host_to_omit2
SendEnv LANG LC_*

    Would be the right answer. Disabling this policy for every host seems a bit too drastic.
