capistrano cannot run ssh: no such file or directory - deployment

Question

I'm new to capistrano and I'm trying to set up a test project, but as you can guess, without much success. When I run cap deploy:update, I get following output:
$ cap deploy
* 2014-12-27 21:48:06 executing `deploy'

And here's the deploy.rb file:
begin
require 'colored'
rescue LoadError
$stderr.puts <<-INSTALL
You need the both the capistrano-ext and colored gems to deploy this application
Install the gems like this:
gem install colored
INSTALL
exit 1
end
set :application, "stocksolutions"
set :repository, "git#github.com:hstandaert/test.git"
set :branch, "production"
set :user, 'stocksolutions.be'
set :deploy_to, "/customers/4/b/b/#{user}/httpd.www/private"
set :use_sudo, false
set :scm, :git
default_run_options[:pty] = true
server "ssh.stocksolutions.be", :app, :web
namespace :deploy do
task :start do ; end
task :stop do ; end
task :restart, :roles => :app, :except => { :no_release => true } do
run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
end
end
Anyone who can spot my mistake?

Answer 1

Your log seems to suggest that either there is no ssh client installed in your deployment server, or the command cannot be found in the server's PATH.
Try if cloning the repo via https instead of ssh will work, by changing the following:
BEFORE
set :repository, "git#github.com:hstandaert/test.git"
AFTER
set :repository, "https://github.com/hstandaert/test.git"
You'll be asked to provide your login credentials for github to be able to clone the repo.
