How to install the latest version of Vagrant

1. Download the Debian package (not the generic Linux zipfile)

2. Look in your Downloads directory for the exact filename. Mine was vagrant_2.2.9_x86_64.deb your filename may vary.

3. Install. Recall that the file is in the Downloads directory, and use the correct filename. On mine it's: sudo apt install ~/Downloads/vagrant_2.2.9_x86_64.deb

Automate the process with a simple script below:

#!/bin/bash

cd /tmp
export VERSION=$(curl -s https://api.github.com/repos/hashicorp/vagrant/tags | jq ".[0].name" | cut -c 3-8)
curl -O https://releases.hashicorp.com/vagrant/$VERSION/vagrant_{$VERSION}_x86_64.deb
chmod 755 vagrant_$(echo $VERSION)_x86_64.deb
sudo apt install ./\vagrant_$(echo $VERSION)_x86_64.deb
rm -f vagrant_$(echo $VERSION)_x86_64.deb

The code will install the latest version of Vagrant.
