When ssh into a production server, Debian, and noticed there is a warning or error as follows:
Terminal
manpath: can't set the locale; make sure $LC_* and $LANG are correct
mkyong@test-server:~$
Check the server’s locale; there are warning about the LC_CTYPE and LC_ALL variables.
Terminal
$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE=UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"

1. Solution (Linux): Reconfigure locales.
On Linux, try to reconfigure the locale to en_US.UTF-8.
Terminal
$ sudo locale-gen "en_US.UTF-8"
Generating locales...
en_US.UTF-8... done
Generation complete.
$ sudo dpkg-reconfigure locales
Generating locales...
en_US.UTF-8... up-to-date
Generation complete.
2. Solution (macOS) : Terminal sets environment variables.
When we login over ssh from macOS to Linux, the terminal default automatically sets environment variables.
In Terminal, clicks Terminal -> Settings... -> Profiles -> Advanced tab. There’s a checkbox for sets environment variables on startup, Uncheck it. Open a new terminal and log in via ssh again; the locale should be correct now.
Does not work
sudo dpkg-reconfigure locales
