Capistrano deploy fails. Using bitbucket and SSH key - ruby-on-rails

Question

I've been trying to solve this problem for some time.
I'm working with Ruby on Rails, using Capistrano to deploy from a BitBucket repository, and when I run cap production deploy it ends up with the following error:

# ======================
# Defines a single server with a list of roles and multiple properties.
# You can define all roles on a single server, or split them:
# server 'example.com', user: 'deploy', roles: %w{app db web}, my_property: :my_value

# role-based syntax
# ==================
# Defines a role with one or multiple servers. The primary server in each
# group is considered to be the first unless any hosts have the primary
# property set. Specify the username and a domain or IP for the server.
# Don't use `:all`, it's a meta role.
# role :app, %w{deploy#example.com}, my_property: :my_value
# role :web, %w{user1#primary.com user2#additional.com}, other_property: :other_value
# role :db, %w{deploy#example.com}

role :db, %w{user#MyHostIP}
# Configuration
# =============
# You can set any configuration variable like in config/deploy.rb
# These variables are then only loaded and set in this stage.
# For available Capistrano configuration variables see the documentation page.
# http://capistranorb.com/documentation/getting-started/configuration/
# Feel free to add new variables to customise your setup.
# Custom SSH Options
# ==================
# You may pass any option but keep in mind that net/ssh understands a
# limited set of options, consult the Net::SSH documentation.
# http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start
#
# Global options

I hope you can help me. I don't know what to do!!
Thank you!

Answer 1

I solved it. The problem was that I didn't configure Capistrano locally.
