«[Beginners Guide to Install Discourse on Ubuntu for Development](https://meta.discourse.org/t/topic/14727)».  
I use the latest stock version of Ubuntu Desktop ([16.04.3 LTS](http://releases.ubuntu.com/xenial/)) which is unmodified, without any extra packages previously installed apart from the guide’s previous steps packages .

The `bundle exec rake autospec` guide’s step fails:

Here’s how to fix this:

```shell
# install jhead
sudo apt-get -y install jhead

# install node.js and svgo
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo npm install -g svgo

```

Updated the install script to install `jhead` as well, need to figure out how to install `svgo` without adding node as dependency.

I believe there is no problem adding `node` deps now that our repo has `package.json` and `yarn.lock`.
