Landscape Package – Fix Landscape Package Not Found on Ubuntu 15.10


I'm trying to install the on-premises Landscape server as shown here: but the "landscape-server-quickstart" package seems to not be found. Here is what I put in the Terminal, and its output:

joseph@slave-server:~$ sudo add-apt-repository ppa:landscape/15.11
[sudo] password for joseph: 
LDS 15.11

And the return of sudo apt-get update:

joseph@slave-server:~$ sudo apt-get update

This is what happens when I try to install either landscape-server-quickstart or landscape-server:

joseph@slave-server:~$ sudo apt-get install landscape-server-quickstart
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package landscape-server-quickstart is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'landscape-server-quickstart' has no installation candidate

I get the same error for "landscape-server".

So far, I have tried this on two physical Ubuntu 15.10 machines, and one DigitalOcean 15.10 VPS, none of them worked. Any clues?

Landscape is only released for Ubuntu LTS releases. Currently the latest LTS is Trusty (Ubuntu 14.04) but in a couple of weeks we'll have the new LTS - Xenial (Ubuntu 16.04).

Please try using an Ubuntu Trusty 14.04 machine, with the Landscape 16.03 release (the page that you linked to has already been updated to reflect that new release).
