== Package Back-Porting Policy ==

The packages in the cloud archive will follow a policy similar to Ubuntu release back-porting policy. For example, Openstack Train originated in Eoan and is back-ported to the Train cloud archive, and Openstack Queens originated in Bionic and is back-ported to the Queens cloud archive.

You may also refer to [[http://reqorts.qa.ubuntu.com/reports/ubuntu-server/cloud-archive/|these tables]] to see what the package version per Openstack release in the cloud archive. Here is an practical case of the qemu package. Openstack train originated in Eoan, and its qemu is 1.4.0-based. The default qemu version of Bionic is 1.2.0-based. Thus 1.4.0 is back-ported to the Bionic Train cloud archive. By using this Bionic Train cloud archive with your Ubuntu Bionic release, the original 1.2.0-based qemu in your Ubuntu Bionic system will be replaced/upgraded to 1.4.0-based qemu.

The Ubuntu Cloud Archive

Canonical’s Ubuntu Cloud Archive (UCA) gives users the ability to install newer releases of OpenStack on an Ubuntu LTS release (only) as they become available up through to the next Ubuntu LTS release. Bug processing and patch contributions will follow standard Ubuntu practice and policy where applicable.

In order to allow for relatively easy upgrades, and still adhere to Ubuntu processes and policy, Canonical elected to have ubuntu-cloud.archive.canonical.com be the home of the cloud archive. Update paths will exist for each OpenStack release. For example, enabling "bionic-ussuri" will provide access to all OpenStack Ussuri packages built for Ubuntu 18.04 LTS (binary and source), any updated dependencies required, and bug/security fixes published after release.

Packages go through various stages as they make their way towards a publicly available UCA release. See the Version Tracking page for details.

Any given UCA OpenStack release can be enabled on exactly one Ubuntu LTS release.

For more details on OpenStack release end of life see: Ubuntu OpenStack release cycle.

Reporting bugs

To report bugs against packages from the UCA, please use the ubuntu-bug tool.

For example:

ubuntu-bug nova-compute

This will ensure that bugs are raised against the cloud-archive project on Launchpad.

Using the UCA

The release schedule of OpenStack and Ubuntu are generally synchronised: a new OpenStack release becomes available in the UCA every six months and coincides with each release of Ubuntu. As OpenStack releases are added to the UCA and as releases fall out of support this section will be updated.

A UCA OpenStack release is enabled on a host with the add-apt-repository command.

Important: It is good practice to run sudo apt update both before and after the add-apt-repository command.

Ubuntu 20.04 LTS

On 20.04, OpenStack Victoria and OpenStack X are supported for 18 months each, and OpenStack W for 36 months. When 22.04's default OpenStack version is released it will be added to the UCA with support for 3 years (i.e. until the end of the Ubuntu 20.04 LTS lifecycle).

Ubuntu 18.04 LTS

On 18.04, OpenStack Rocky and OpenStack Train are supported for 18 months each, and OpenStack Stein for 36 months. When 20.04's default OpenStack version is released it will be added to the UCA with support for 3 years (i.e. until the end of the Ubuntu 18.04 LTS lifecycle).

sudo add-apt-repository cloud-archive:ussuri

Train

sudo add-apt-repository cloud-archive:train

Stein

Ubuntu 16.04 LTS

On 16.04, OpenStack Newton and OpenStack Pike are supported for 18 months each, and OpenStack Ocata for 36 months. OpenStack Queens, 18.04's default OpenStack version, is supported in the UCA for 3 years (i.e. until the end of the Ubuntu 16.04 LTS lifecycle).

Queens

sudo add-apt-repository cloud-archive:queens

Ubuntu 14.04 LTS

On 14.04, OpenStack Juno and OpenStack Liberty are supported for 18 months each, and OpenStack Kilo for 36 months. OpenStack Mitaka, 16.04's default OpenStack version, is supported in the UCA for 3 years (i.e. until the end of the Ubuntu 14.04 LTS lifecycle).

Mitaka
