For Ubuntu 16.04 or 14.04 LTS

You can install Landscape directly on a machine running Ubuntu 14.04 LTS, this is called "Landscape On Premises." It is free for up to 10 physical (or virtual) machines and 50 containers:

Deploying a single server

WARNING: landscape-quickstart modifies apache configuration files, DO NOT DO THIS ON AN EXISTING SERVER INSTALLATION without understanding what you are getting into.

Just install the Landscape Quickstart package: Check here for changes to the below instructions:

sudo add-apt-repository ppa:landscape/17.03 sudo apt-get update sudo apt-get install landscape-server-quickstart

After it finishes, access it with a browser like https://hostname.example.com/

Where hostname.example.com is the output of hostname -f on that machine, or just hostname if that fails to resolve.

Using Landscape

You should then see the web UI after filling in your name and contact details:

Click on the link highlighted to add client machines:

Follow those instructions on the client you want to join to Landscape. Note the following line:

sudo landscape-config --computer-title "My Web Server" --account-name standalone --url https://<servername>/message-system --ping-url http://<servername>/ping

You can customize the title and so forth for each machine. See the landscape-config man page for more information.

After you type in the landscape-config command the client will ask you some questions, those are optional, you can just hit Enter until the client restarts, then you can accept the client in the web UI.

Registering clients with a self signed certificate:

The quickstart package installs a self-signed certificate that is generated on-the-fly.

Grab this file from the server: /etc/ssl/certs/landscape_server_ca.crt

Copy it somewhere on the client, for example, /etc/landscape/landscape_server_ca.crt

Change /etc/landscape/client.conf to include this line, pointing at the file you just copied: ssl_public_key = /etc/landscape/landscape_server_ca.crt

Then try to register again. (Thanks to panlinux for figuring this out)
