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
Generating locales (this might take a while)...
  en_US.UTF-8... done
Generation complete.

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

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.

  • This is the right solution. – Martin Braun Jun 28 '21 at 21:38
  • LC_CTYPE should be empty by default. I don’t think a properly configured macOS should set this variable. If you see this environment variable I think people should check their macOS language configuration. – Franklin Yu Oct 26 '22 at 08:58

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

unset LC_CTYPE in ~/.profile

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.

perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset)

For me work just exsport this two $ export LC_ALL=C.UTF-8 $ export LANG=C.UTF-8
