Question

I am trying to deploy openstack using devstack on ubuntu 18.04 LTS. My env is behind proxy which I have configured in both bashrc and apt.

During the deployment I am facing below error. unstack and clean is also not helping this issue.

What can I try to resolve this?

Answer 1

It seems your credentials are mismatch between services. You are getting Forbidden (HTTP 403) which means either:

1. Your service credentials are incorrectly populated.
2. Your proxy is stopping access to http://10.94.60.19/identity . Try to set "no_proxy" environment variable for the same and check if you can access it.
