Please change `scm` setting to `:git`.

Hi guys,

This seems to be the same as issue #9

Maybe I am missing something but I just cant not get passed this.

Setup is:
Rails Version: 5.1.6
Cap Version: 3.11.0 (Rake Version: 12.3.1)
capistrano-ssh-doctor version: 1

Capfile:

require "capistrano/setup"
require "capistrano/deploy"

require "capistrano/scm/git"
install_plugin Capistrano::SCM::Git

require 'capistrano/rbenv'
require 'capistrano/rbenv_install'

require 'capistrano/bundler'
require 'capistrano/rails'

require 'capistrano/unicorn_nginx'
require 'capistrano/postgresql'

require 'capistrano/safe_deploy_to'
require 'capistrano/ssh_doctor'

Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }

deploy.rb

lock "~> 3.11.0"
set :rbenv_ruby, "2.5.1"

set :application, "some_app"
set :repo_url, "git@github.com:wonderphil/some_app.git"

Gemfile

....
group :development do
  gem "capistrano", "~> 3.10"                
  gem 'capistrano-rbenv'                     
  gem 'capistrano-rbenv-install'             
  gem 'capistrano-bundler'                  
  gem 'capistrano-rails'                     
  gem 'capistrano-unicorn-nginx'             
  gem 'capistrano-postgresql'                
  gem 'capistrano-safe-deploy-to'            
  gem 'capistrano-ssh-doctor'
end
....

when I run:

$ cap production ssh:doctor
It seems you are NOT using git as a Capistrano strategy. At the moment capistrano-ssh-doctor supports only git.
Please change `scm` setting to `:git`.

If i add the scm setting i get

$ cap production ssh:doctor
[Deprecation Notice] `set :scm, :git` is deprecated.
To ensure your project is compatible with future versions of Capistrano,
remove the :scm setting and instead add these lines to your Capfile after
    `require "capistrano/deploy"`:

    require "capistrano/scm/git"
    install_plugin Capistrano::SCM::Git

Any help?

Hi. I was searching the same issue.

Actually this issue has been fixed long time ago but apparently gem has not updated.

You can simply workaround using the master branch in Gemfile as:

gem 'capistrano-ssh-doctor', git: 'https://github.com/capistrano-plugins/capistrano-ssh-doctor.git'

Just installed capistrano-ssh-doctor and I am getting the exact same issue as @wonderphil. I tried the above by @sinankeskin but it did not change anything. Any ideas?

Hi @Megaheff

Looks like my solution still works. Use git repo for workaround.

I wanted to let anyone else who finds their way here, that on my Rails 7, Ruby 3.0.2 app with a current version of Capistrano (3.16) I still receive this error even if I use the master branch as described above.

@sinankeskin the solution still works
