This is expected when there's no display server running (as is the case with an SSH session unless X forwarding is used)—librecaptcha needs to display images and can't do that over a plain text-based SSH session.

There should be a better error message than a “Broken pipe” traceback, though—I'll look into improving that when I have time.

Hello

Thanks for your reply. As we have an option LIBRECAPTCHA_NO_GUI I have understood was possible to use on only cli mode.
