How to download and install Heroku?

Just tried this now on 14.04. Here is how I did it, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh

Once it finished installing, I typed heroku apps. see image below for more info.

You can install Heroku on Ubuntu 14.04 or any later version as a snap:

sudo snap install --classic heroku

This is published directly by Heroku. It updates automatically whenever they release a new version.

The more adventurous can install from the edge channel and get updates for every upstream commit:

sudo snap install --classic --edge heroku

Configuring Heroku is quite straight-forward on DigitalOcean. After ssh-ing, run the following commands with sudo:

wget https://cli-assets.heroku.com/heroku-cli/channels/stable/heroku-cli-linux-x64.tar.gz -O heroku.tar.gz
tar -xvzf heroku.tar.gz
sudo mkdir -p /usr/local/lib /usr/local/bin

List the content of the current directory with ls. I found this output:

heroku-cli-v6.15.22-3f1c4bd-linux-x64  
heroku.tar.gz

This output determines the value in the next step, use the first file name in the next command:

sudo mv heroku-cli-v6.15.22-3f1c4bd-linux-x64 /usr/local/lib/heroku
sudo ln -s /usr/local/lib/heroku/bin/heroku /usr/local/bin/heroku

And that's it.
