The setup wizard should identify that the requests fail, and offer to configure a proxy, or let you skip plugin installation. Do some of the requests pass? If so, it might be different from a basic "no networking" situation in ways not anticipated. That said, the setup wizard has fairly little value if Jenkins is offline. You can bypass <https://www.jenkins.io/doc/book/managing/system-properties/#jenkins-install-runsetupwizard> it, but note that it'll start with authorization + authentication set so that anonymous users are admins; so you'll want to customize things quickly on startup, e.g. with an init.groovy <https://www.jenkins.io/doc/book/managing/groovy-hook-scripts/#post-initialization-script-init-hook> script, ideally before exposing the HTTP port to anyone other than localhost. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
