Distributions might release OpenStack packages as part of their distribution or through other methods because the OpenStack and distribution release times are independent of each other.
This section describes the configuration you must complete after you configure machines to install the latest OpenStack packages.
To use the Ubuntu Cloud Archive for Icehouse
The Ubuntu Cloud Archive is a special repository that allows you to install newer releases of OpenStack on the stable supported version of Ubuntu.

|---|---|
Icehouse is in the main repository for 14.04 - this step is not required. |
Install the Ubuntu Cloud Archive for Icehouse:
# apt-get install python-software-properties # add-apt-repository cloud-archive:icehouse
Update the package database and upgrade your system:
# apt-get update # apt-get dist-upgrade
If you intend to use OpenStack Networking with Ubuntu 12.04, you should install a backported Linux kernel to improve the stability of your system. This installation is not needed if you intend to use the legacy networking service.
Install the Ubuntu 13.10 backported kernel:
# apt-get install linux-image-generic-lts-saucy linux-headers-generic-lts-saucy
Reboot the system for all changes to take effect:
# reboot
