Ubuntu Linux Basic Setup

Trellis, Bedrock, and Sage development on Ubuntu Linux is supported by several libraries and software packages. This guide describes how to get the following packages installed and configured on your computer:

  • Git
  • Composer


Git is available from the standard Ubuntu software repositories and may be installed with the following command:

$ sudo apt-get install git

Configure Git with your user information:

$ git config --global user.name "Your Name"
$ git config --global user.email "yourname@example.com"


Install Composer from the standard Ubuntu software repositories:

$ sudo apt-get install composer

SSH Keys

Create SSH Keys

Trellis and GitHub both use SSH keys to communicate securely without the need to type a username and password each time. Create your SSH keys:

$ ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

For more details on generating SSH keys, see GitHub's excellent documentation.

Add your SSH key to the ssh-agent

Modify your ~/.ssh/config file to automatically load keys into the ssh-agent and store passphrases in your keychain.

Edit your ~/.ssh/config file and add the following lines:

Host *
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/id_rsa
