title: Rails bundle install Could not find turbo-rails-7.1.1 in any of the sources
body: <p>On a brand new digitalocean droplet running Ubuntu 20.10 with a brand new pretty near empty rails 7 alpha 2 app running <code>bundle install</code> results in the following both when running cap production deploy on my local machine and when running from the command shell on the droplet</p>
  <pre><code>Fetching gem metadata from https://rubygems.org/............
  Could not find turbo-rails-7.1.1 in any of the sources
  </code></pre>
  <p>I have no issues locally with this so this has to be an environment issue on the production server or some configuration option I've missed somehere.
  I am using latest stable rvm which is correctly configured,</p>
  <pre><code>rvm gemset list
  
  gemsets for ruby-3.0.0 (found in /home/comtechmaster/.rvm/gems/ruby-3.0.0)
     (default)
     global
  =&gt; master_cms
   
  </code></pre>
  <p>I used a capistrano script to deploy the app and latest stable version node was installed using nvm.
  Bundler is the same version on both environments and turbo-rails-7.1.1 does not appear anywhere in my gemfile.lock</p>
