Known issue: HTTP 403 error in "bundle install --verbose" output

When running bundle install --verbose on Bundler versions 1.12+, you might see errors of the form

HTTP 403 Forbidden

These errors are not fatal, Rails LTS should still be installed correctly. This has been tested with all Bundler versions 1.12.x and 1.13.x.


Since version 1.12, Bundler includes a performance optimization called "compact gem index". Our gem server does not support this.

When trying to access this new index our web server will return a 403. Bundler will log this to its output, but then fall back to using the old style index and proceed as usual.
