sudo fails because the password prompt doesn't work

[pedrocr]

I've just started to try supply_drop to replace the traditional puppetmaster setup I am using. I did a minimal test and couldn't get it to work because the sudo password prompt doesn't get passed on to my terminal. Here's the output of a cap run:

$ cap puppet:unlock
  * 2013-05-13 22:23:52 executing `puppet:unlock'
  * executing "sudo -p 'sudo password: ' rm -f /tmp/puppet.lock; true"
    servers: ["golias.fernandocabral"]

My Capfile is minimal:

require 'rubygems'
require 'supply_drop'

ssh_options[:paranoid] = false 
server "golias.fernandocabral", :general

Both my machine and the server I was pushing to are Ubuntu 12.04 LTS installs. Capistrano is version 2.15.4 and supply_drop is version 0.15.0

Try adding this line to your Capfile

default_run_options[:pty] = true

Yep, that solves it. None of the examples have that line. I see that it's a capistrano option so I guess supply_drop can't do anything about it. Thanks for the quick reply.
