The Ubuntu Cloud Archive
Canonical’s Ubuntu Cloud Archive (UCA) gives users the ability to install backported OpenStack versions on Ubuntu LTS releases.
The Ubuntu and OpenStack projects publish new releases every six months at approximately the same time. Each Ubuntu release therefore includes a new OpenStack version by default. It is this OpenStack version that is backported to the latest LTS via the UCA. The Ubuntu OpenStack release cycle graphic represents this scheme visually over time.
SRU process
The SRU process for OpenStack and the UCA is used during the development of a new UCA release and when backporting any updated dependencies and bug/security fixes to an existing UCA release.
For example, in terms of a new UCA release, Ubuntu Kinetic ships with OpenStack Zed by default. In this timeframe, the latest LTS is Ubuntu 22.04 (Jammy). Zed packages (binary and source) are therefore backported to Jammy via the Zed UCA release. In order for this to happen, individual Kinetic packages are backported according to this staged process:
kinetic -> zed-staging -> zed-proposed -> zed-updates
When backporting fixes to an existing UCA release the original Ubuntu release must also get the update:
kinetic-proposed -> zed-staging -> zed-proposed -> kinetic-updates -> zed-updates
When Kinetic reaches end-of-life, Zed package updates will be uploaded directly to the Zed UCA (kinetic stage).
This process can be monitored live with the Ubuntu Cloud Archive Tracker. It includes package versions for each of the above stages and for all UCA releases. The first column in the tracker is Ubuntu and represents the first stage in the above two scenarios.
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 (it is recommended to run sudo apt update both before and after).
Ubuntu 22.04 LTS
On 22.04, OpenStack Zed is supported for 18 months.
Zed
sudo add-apt-repository cloud-archive:zed
Ubuntu 20.04 LTS
On 20.04, OpenStack Victoria and OpenStack Xena are supported for 18 months each, and OpenStack Wallaby 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).
Yoga
sudo add-apt-repository cloud-archive:yoga
Xena
sudo add-apt-repository cloud-archive:xena
Wallaby
sudo add-apt-repository cloud-archive:wallaby
Ubuntu 18.04 LTS
On 18.04, OpenStack Rocky and OpenStack Train are supported for 18 months each, and OpenStack Stein for 36 months. OpenStack Ussuri, 20.04's default OpenStack version, is supported in the UCA for 3 years (i.e. until the end of the Ubuntu 18.04 LTS lifecycle).
Ussuri
sudo add-apt-repository cloud-archive:ussuri
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

Reporting a bug
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.
