I have followed https://www.rdoproject.org/Quickstart to install openstack in a CentOS virtualbox.

I got the following error output while running sudo yum install -y openstack-packstack

Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Install Process
Loading mirror speeds from cached hostfile
* base: centos.excellmedia.net

Trying other mirror. 
Error: Cannot retrieve repository metadata (repomd.xml) for repository:   openstack-kilo. Please verify its path and try again

This url is not accessible from other machines as well. CentOS VM have the internet connection as well. Appreciate your help in resolving this.

What's wrong with actually trying the URL:

  1. If you navigate manually, you are switched to HTTPS:


  2. Since you are on CentOs 7, simply specify:


... in /etc/yum.repos.d where there's a .repo file with the wrong URL in it.

  • where can I specify this url?.

  • @apremalal - in the /etc/yum.repos.d/ directory there's a .repo file with incorrect url. Fix it and you're done. Jul 23, 2015 at 16:08
