How can I fix this ?

Hi,

This issue happens when you try to install on a Linux server after doing a SSH connection from a Mac. It is caused by an invalid locale (internationalization) setting on your Mac.

A little known property of the ssh client is that it is able to forward your locale settings so that after remotely connecting, you find yourself with a properly localized machine. Your mac has "UTF-8" as setting for some parts of the locale, which is not valid for your Linux box.

You probably receive a warning when opening the SSH connection like:

-bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory

You can fix this on your Mac side by adding this to your .profile (or .bashrc) file:

export LANG=en_US.UTF-8

export LC_ALL=en_US.UTF-8

You can also add this on your .profile (or .bashrc) file on the Linux box itself:

export LANG=en_US.UTF-8

export LC_ALL=en_US.UTF-8

After logging out and logging back in, run "locale" on the Linux box, which should not display any error anymore. DSS install will now work properly.
