Dependency installation steps for Debian GNU/Linux 9.x (stretch)

This document assumes you are starting from a fresh install of Debian in the 9.x series.

Most recently tested 2019-02-13 with the following debian release:

$ lsb_release --description
Description:	Debian GNU/Linux 9.7 (stretch)

Set up Debian backports

This will aid in the installation of VirtualBox.

Add stretch-backports to your system's apt sources with 'main' and 'contrib' entries.

echo "deb http://ftp.debian.org/debian stretch-backports main contrib" | sudo tee /etc/apt/sources.list.d/stretch-backports.list

You may also select a different mirror site from Debian's list at https://www.debian.org/mirror/list

For instance, to instead use Debian's primary United States mirror:

echo "deb http://ftp.us.debian.org/debian stretch-backports main contrib" | sudo tee /etc/apt/sources.list.d/stretch-backports.list

Update your local package index

sudo apt update

Install VirtualBox

sudo apt install virtualbox

Most recently tested 2019-02-13 with the following virtualbox release:

$ virtualbox --help
Oracle VM VirtualBox Manager 5.2.24_Debian
...

Install git

$ sudo apt install git

Most recently tested 2019-02-13 with the following git release:

$ git --version
git version 2.11.0

Install Vagrant 2.0.3 or higher

As of this writing, the Vagrant version that Debian uses in its "stretch" release is 1.9.x so we suggest getting a package from Vagrant's web site:

wget -c https://releases.hashicorp.com/vagrant/2.2.3/vagrant_2.2.3_x86_64.deb
sudo dpkg -i vagrant_2.2.3_x86_64.deb
rm vagrant_2.2.3_x86_64.deb

Most recently tested 2019-02-13 with the following vagrant release:

$ vagrant --version
Vagrant 2.2.3

Install pip (python package manager)

We'll use this to install ansible, so we can be on a more current version of ansible than the one Debian provides with its 'stretch' distribution.

sudo apt install python-pip

Most recently tested 2019-02-13 with the following pip release:

$ pip --version
pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)

Install ansible 2.4.x or higher

pip install --user -U ansible

This will place an ansible executable in ~/.local/bin, so add the following to ~/.bashrc:

# set PATH so it includes user's private .local/bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

Then restart your shell or source .bashrc in your shell session:

$ source .bashrc

Most recently tested 2019-02-13 with the following ansible release:

$ ansible --version
ansible 2.7.7
...

Install GnuPG 2.x (2.1.18 or greater)

This is likely already installed and runnable via 'gpg'

$ gpg --version
gpg (GnuPG) 2.1.18

We want to be able to run it using the command 'gpg2'. For that we can install the gnupg2 package.

According to the description of that package, “This is a dummy transitional package that provides symlinks from gpg2 to gpg.” https://packages.debian.org/stretch/gnupg2

$ sudo apt install gnupg2

Most recently tested 2019-02-13 with the following GnuPG release:

$ gpg2 --version
gpg (GnuPG) 2.1.18
