Capistrano SSH::AuthenticationFailed, not prompting for password

capistrano, deployment, ruby, ruby-on-rails

Solution

Figured it out! Apparently this issue was with `net-ssh` gem. I had version 2.8.0 installed recently with some updates to my development environment and was the cause.

I'm not sure why it was failing, but `gem uninstall net-ssh -v 2.8.0<` fixed it for me.

If anyone actually knows why this was an issue or how I can correct this issue with the newer version of `net-ssh` I'd be interested to hear it.

Problem

I've been using capistrano successfully for a while now and all of a sudden in every project I've lost the ability to deploy. Environment: - os X (Mavericks) - ruby 1.9.3p194 - rvm (locally, not on server) - rails 3.2 and up - RubyGems 1.8.25 I'm not using rsa_keys or anything I want capistrano to prompt for user and password. Suddenly it has decided not to ask for a password, but does ask for user. Then it rolls back and gives me the following error. ``` [deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: sub.example.com (Net::SSH::AuthenticationFailed: Authentication failed for user user@sub.example.com) connection failed for: sub.example.com (Net::SSH::AuthenticationFailed: Authentication failed for user user@sub.example.com) ``` This has occurred on my personal laptop and my iMac at work. It occurs when deploying to two different servers (both linux) I'm completely at a loss here. Any ideas?
