Rails bundle install Could not find turbo-rails-7.1.1 in any of the sources
I ran into this also. Not sure why, but they yanked the 7.x versions and regressed to 0.8.x:
https://rubygems.org/gems/turbo-rails/versions/7.1.1
Just add this to your Gemfile:
gem 'turbo-rails', '~> 0.8'
And then run and run ./bin/bundle update turbo-rails and you should be good.
In my case removing Gemfile.lock and running install again worked.
