I have installed my project on a new comptuter. This project have Capifony (Capistrano). But now, when I want update my website with "cap deploy", I get this error :

[deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: 37...* (ArgumentError: Value(s) have been set to nil: password) connection failed for: 37...* (ArgumentError: Value(s) have been set to nil: password)

My configuration file has not changed is the same as on my old computer ... I don't understand. Thanks :)

Answer 1

I was able to solve this with help of my colleagues. In my case i had net-ssh gem installed of version 4.0.0.alpha4. What I had to do is to downgrade it to 3.1.1.

sudo gem install net-ssh --version 3.1.1

Then uninstall newer version:

sudo gem uninstall net-ssh

Choose option 1. net-ssh-4.0.0.alpha4
