Is there currently a way to install Ubuntu Openstack with Landscape?

We tested the installation with the two images (16.04.3, 17.10).
We have followed the installation instructions from the following links.

1. https://www.ubuntu.com/download/cloud/build-openstack

we start conjure-up (sudo snap install conjure-up --classic)
Landscape is not displayed under other


2. https://insights.ubuntu.com/2014/11/...-on-autopilot/

sudo add-apt-repository ppa:cloud-installer/stable
Cannot add PPA: 'ppa:~cloud-installer/ubuntu/stable'.
The team named '~cloud-installer' has no PPA named 'ubuntu/stable'
Please choose from the following available PPAs:

sudo apt install openstack
Package openstack can not be found
can someone help me with this?
The MAAS server is installed and is working. The OpenStack installation with Landscape does not work.
