Create Puma Upstart Script

Tutorial in https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-git-hooks-on-ubuntu-14-04 mentions to create the puma upstart script by running two wget commands in the production server (after changing directory to home “cd ~”: 1.- wget https://raw.githubusercontent.com/puma/puma/master/tools/jungle/upstart/puma-manager.conf 2.- wget https://raw.githubusercontent.com/puma/puma/master/tools/jungle/upstart/puma.conf

Both of them throw the 404: Not Found error.

Question is, what other options do I have to do this? or am I doing something wrong?

Full output is:
