Script to install on Ubuntu 15.10(and possibly other systems)

I wrote up a script to install cups-connector on Ubuntu 15.10 and it might work on other systems that use systemd too? Forgive me if it's ugly, I'm not what you'd call a shell script master by any means. I mostly just Googled how to do what I wanted it to do. Anyway here it is. Tested to work on my desktop and home server.(Both Ubuntu 15.10) I wanted to post it up here to see if it's something you'd like in the wiki and to get other people's input on it.

#!/bin/bash

w=`tput setab 7`
r=`tput setaf 1`
g=`tput setaf 2`
y=`tput setaf 3`
b=`tput setaf 4`
d=`tput sgr0`
latest_release=2015.10.05

#Install dependencies if the script is run on an Ubuntu machine:
if [[ $(uname -v | grep -F 'Ubuntu') = *Ubuntu* ]]; then
    sudo apt-get install libcups2 libavahi-client3 avahi-daemon

#Download & extract the correct version of the latest binaries:
if [[ $(uname -i | grep -Fx 'x86_64') = *x86_64* ]]; then
    wget https://github.com/google/cups-connector/releases/download/$latest_release/gcp-cups-connector-linux-amd64-$latest_release.tar.gz
    tar -xzvf gcp-cups-connector-linux-amd64-$latest_release.tar.gz
