为ubuntu添加不同版本openstack源

首先：

# apt-get install software-properties-common

再选择版本（ubuntu版本与openstack版本存在对应支持的关系，不支持的版本可能无法安装）：

Liberty

NOTE: Liberty cloud archive only supported on Trusty

sudo add-apt-repository cloud-archive:liberty

Kilo

NOTE: Kilo cloud archive only supported on Trusty

sudo add-apt-repository cloud-archive:kilo

Juno

NOTE: Juno cloud archive only supported on Trusty

sudo add-apt-repository cloud-archive:juno

Icehouse

NOTE: Precise only - Icehouse is the base Openstack release in Trusty

sudo add-apt-repository cloud-archive:icehouse

Then run:
sudo apt-get update

to update your package listings and then proceed to install/upgrade your openstack packages.
