Ubuntu Linux

System update

Run a general system update:

sudo apt update


Git is officially maintained in Ubuntu:

sudo apt install git

Ruby version manager

Ruby versions packaged in official repositories are not suitable to work with Consul Democracy, so we'll have to install it manually.

First, we need to install Ruby's development dependencies:

sudo apt install libssl-dev autoconf bison build-essential libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm5 libgdbm-dev

The next step is installing a Ruby version manager, like rbenv:

wget -q https://github.com/rbenv/rbenv-installer/raw/main/bin/rbenv-installer -O- | bash
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
source ~/.bashrc


To compile the assets, you'll need a JavaScript runtime. Node.js is the preferred option.

Run the following command on your terminal:

sudo apt install nodejs


Install postgresql and its development dependencies with:

sudo apt install postgresql libpq-dev

You also need to configure a user for your database. As an example, we'll choose the username "consul":

sudo -u postgres createuser consul --createdb --superuser --pwprompt

To make sure the UTF-8 enconding is used, create a file:

sudo nano /etc/profile.d/lang.sh

Add the following:

export LANGUAGE="en_US.UTF-8"
export LANG="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"

Reconfigure Postgres to use the UTF-8 encoding:

sudo su - postgres
update pg_database set datistemplate=false where datname='template1';
drop database Template1;
create database template1 with owner=postgres encoding='UTF-8'
lc_collate='en_US.utf8' lc_ctype='en_US.utf8' template template0;
update pg_database set datistemplate=true where datname='template1';



Install Imagemagick:

sudo apt install imagemagick


To run E2E integration tests, we use Selenium along with Headless Chrome.

To get it working, install the chromium-chromedriver package and make sure it's available on your shell's PATH:

sudo apt install chromium-chromedriver
sudo ln -s /usr/lib/chromium-browser/chromedriver /usr/local/bin/

Now you're ready to go get Consul Democracy installed!
