Jamis, I actually found out a way to get this working without an
interactive prompt.
require 'capistrano/cli'
Capistrano::Configuration.instance(:must_exist).load do
namespace :ubuntu do
desc "update apt packages"
task :apt_update do
invoke_command "apt-get -qyu update", :via => run_method
invoke_command "apt-get -qyu upgrade", :via => run_method
invoke_command "apt-get -qyu autoclean", :via => run_method
end
end
end
I'll try your idea out as well. Thanks for the tip!
