Vulcan: MupX deployment fails. Why?

I’m trying to deploy Telescope to a simple Ubuntu 16.04 server. So I’m using the suggested deployment with MupX. After setting up the mup.json file, I did a mupx deploy:

$ mupx setup

No problems there, so after this I tried a mupx deploy, but that ends with an error:

In these logs I read something about React not being installed. But as far as I can see, it installs Telescope into a Docker container, and I don’t really know how I can install react within that container.

Does anybody have any idea what I can do to fix this?
