A complete guide to setup vagrant on Ubuntu 18.04

Install VirtualBox

Start by importing GPG keys of the Oracle Virtualbox repository:

wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -

wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -

Both commands should output OK which means that keys are successfully imported and packages from this repository are trusted.

Next add virtual box APT repository:

sudo add-apt-repository "deb [arch=amd64] http://download.virtualbox.org/virtualbox/debian $(lsb_release -cs) contrib"

$(lsb_release -cs) will print the Ubuntu codename. For example, if you have Ubuntu version 18.04 the command will print bionic.

If you get an error message saying add-apt-repository command not found then you need to install the software-properties-common package.

Once the Virtualbox repository is enabled, update the apt package list and install the latest version of Virtualbox:

sudo apt update

sudo apt install virtualbox-6.0

Now Virtualbox is installed on your Ubuntu system, start:

virtualbox

Installing Vagrant

update package list:

sudo apt update

Download the Vagrant package:

curl -O https://releases.hashicorp.com/vagrant/2.2.6/vagrant_2.2.6_x86_64.deb

NOTE
if curl is not installed :

sudo apt install curl

Now try to download the Vagrant package again

Once the .deb file is downloaded, install it:

sudo apt install ./vagrant_2.2.6_x86_64.deb

Verify Vagrant installation:

vagrant --version

The output should be similar to

Vagrant 2.2.6

Getting Started with Vagrant

Now Vagrant is installed on your Ubuntu system let's create a development environment.
The first step is to create root directory for project which will contain Vagrantfile file. Vagrantfile is a Ruby file that contain configurations and provision the virtual machine.

mkdir ~/my-first-vagrant-project

cd ~/my-first-vagrant-project

Next initialize a new Vagrantfile (will create vagrant file):

vagrant init

and specify the box you want to use.

(You can search other boxes on this link https://app.vagrantup.com/boxes/search we’ll use ubuntu/trusty64)

'vagrant init ubuntu/trusty64`

Now create and configure the virtual machine as specified in the Vagrantfile:

vagrant up

Next update changes in Vagrantfile:

vagrant provision

Next reload vagrant and virtual box:

vagrant reload

To ssh into the virtual machine:

vagrant ssh

Can stop the virtual machine:

vagrant halt

Can destroys all resources(be careful):

vagrant destroy
