Global 404 page for a multilingual site

[alexandros]

Actually there is a much simpler way and I am cross posting it, because if anyone finds this topic via the forum search they need to know that there is no need for shell commands.

See:

Customize 404 Page with Github Page

Generate the project locally and then simply copy the 404.html from the language directory under /static/. The staticDir lives outside Hugo’s Multilingual Mode, therefore a 404.html under the root of /static/ will be served under the root of the domain without having to use any shell command during deployment.
