Re: [Rdo-list] Devstack - why it uninstalls python-virtualenv?

When I'm installing DevStack, it performs the following: ++ FORCE_FIREWALLD=False ++ [[ rhel7 =~ (f20) ]] ++ uninstall_package python-virtualenv ++ is_ubuntu ++ [[ -z rpm ]] ++ '[' rpm = deb ']' ++ is_fedora ++ [[ -z CentOS ]] ++ '[' CentOS = Fedora ']' ++ '[' CentOS = 'Red Hat' ']' ++ '[' CentOS = CentOS ']' ++ sudo yum remove -y python-virtualenv Loaded plugins: fastestmirror, rhnplugin This system is receiving updates from RHN Classic or Red Hat Satellite.
