Package tree is available in Universe. Check that you have it enabled:

enter image description here

Then just do the usual

$ sudo apt-get update
$ sudo apt-get install tree

All Ubuntu repositories (main, universe, restricted, multiverse) can be enabled by following command:

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse"

  • Well I can't see universe anywere in that line... Make sure universe is not commented and dont forget to run sudo apt-get update. Either way in that link you can download the file and install it using Software Center – Salem Oct 24 '15 at 22:29
