Can't continue install on "decidim decidim-app" step

[polnetwork]

Hi, I'm on a clean Ubuntu 18.04 server installation. I'v gone until step "decidim decidim-app" without errors after changing the sources.list from here https://stackoverflow.com/questions/51778272/unable-to-install-phusion-passenger-on-ubuntu-server-18-04 Maybe there's a problem with the bundler? Thank's for all!

Here's the output of my console:

There's definitively something with the bundler or another more obscure involved gem. Another user pointed the same thing. I will have to repeat the process and use 0.16 instead of 0.14.

As this is related to #19 I will continue the conversation there
