The instruction looks like it contains a lot of unnecessary nonsense. I recommend reading with Capistrano Setup .
At a minimum, to install capistrano you need:

1. Understand what tools are needed for deployment: rvm, bower, etc ...
   
2. Add everything you need to Gemfile

   # Use Capistrano for deployment
   group :development do
     gem 'capistrano'
     gem 'capistrano-rails'
     gem 'capistrano-bundler'
     gem 'capistrano-rvm'
     gem 'capistrano-passenger'
     gem 'capistrano-bower'
   end

3. Uninstall applicationbundle exec cap install
4. Require all these modules in Capfile
   

   require 'capistrano/rvm'
   require 'capistrano/bundler'
   require 'capistrano/rails'
   require 'capistrano/bower'
   require 'capistrano/passenger'

   
   
5. Populate minimalist config/deploy.rb
   

   # config valid only for current version of Capistrano
   lock '3.3.5'
   
   set :application, 'my_awesome_site'
   set :repo_url, '[email protected]:username/my_awesome_site.git'
   
   # Default deploy_to directory is /var/www/my_app_name
   set :deploy_to, "/home/user/www/#{fetch(:application)}"
   
   # Default value for :scm is :git
   set :scm, :git

   
   
6. Set deployment environment specific options in config/deploy/production.rb
   

   role :app, %w{myhosting.ru}
   role :web, %w{myhosting.ru}
   role :db,  %w{myhosting.ru}
   
   
   # Extended Server Syntax
   # ======================
   # This can be used to drop a more detailed server definition into the
   # server list. The second argument is a, or duck-types, Hash and is
   # used to set extended properties on the server.
   
   server 'myhosting.ru', user: 'user', roles: %w{web app db}
   set :rails_env, 'production'
   
   set :rvm_type, :user                     # Defaults to: :auto
   set :rvm_ruby_version, '[email protected]'      # Defaults to: 'default'

   
   
7. Everything. Then do it bundle exec cap production deploy:checkand do it for a long time bundle exec cap production deploycatching deployment errors and fixing them :)

Unfortunately, capistrano is not something that can be debugged remotely in psychic fashion.
I would advise only to break the task into steps and arm yourself with debugging.
maybe the deployer user needs sudo, maybe he doesn't have the keys, you can't just say that.
Capistrano doesn't have the best debug messages.
See which user is deploying. What are his rights. Which commands are executed and which are not. Look at all the logs you can find. Try to transfer the sources to bitbucket for the sake of testing.
