Deploying capistrano fails by ssh error when running `bundle install`

Question

I'm using Capistrano 3 to deploy a Rails project to VPS server(CentOS 6.5).

Last time about 2 month ago I could deploy without problem, but now I can't deploy by ssh error when running bundle install at the VPS server.

I updated ruby version 2.0.0-p451 to 2.1.1 , but it doesn't change error message.

This is the error messages:

INFO[057e025d] Running RBENV_ROOT=/usr/local/rbenv RBENV_VERSION=2.1.1 /usr/local/rbenv/bin/rbenv exec bundle install --binstubs /var/www/example.com/shared/bin --path /var/www/example.com/shared/bundle --without development test --deployment --quiet on example.com

I could install rake (10.3.2) by # gem install rake at the server manually like this:

rake's executable "rake" conflicts with /usr/local/rbenv/versions/2.1.1/bin/rake
Overwrite the executable? [yN]  y
Successfully installed rake-10.3.2
Parsing documentation for rake-10.3.2
Installing ri documentation for rake-10.3.2
Done installing documentation for rake after 2 seconds
1 gem installed

But even after updating the deploy error persists same.

What should I do to remove the error? Any suggestions are appreciated.

Answer 1

It looks like the server "au-m.rubygems.org" was down.

That was the reason of the error.
