OpenStack packages for Ubuntu
Ubuntu releases OpenStack with each Ubuntu release. Ubuntu LTS releases are provided every 2 years. OpenStack packages from interim releases of Ubuntu are made available to the prior Ubuntu LTS via the Ubuntu Cloud Archive.
OpenStack Queens is available directly using Ubuntu 18.04 LTS and OpenStack Mitaka is available directly using Ubuntu 16.04 LTS without having to enable an Ubuntu Cloud Archive pocket.
Note
The set up of OpenStack packages described here needs to be done on all nodes: controller, compute, and Block Storage nodes.
Warning
Your hosts must contain the latest versions of base installation packages available for your distribution before proceeding further.
Note
Disable or remove any automatic update services because they can impact your OpenStack environment.
Enable the Ubuntu Cloud Archive pocket as needed

# apt install software-properties-common

OpenStack Queens for Ubuntu 16.04 LTS:
# apt install software-properties-common
