In this tutorial, we will show you how to install Postman on Ubuntu 20.04 LTS. For those of you who didn’t know, Postman is an API development tool that simplifies the process of building, testing, and modifying APIs. It supports various HTTP methods, including GET, POST, PUT, DELETE, and PATCH, and offers features such as environment management, request scripting, and automated testing. Postman is available as a native app for macOS, Linux, and Windows, making it a versatile tool for developers across different platforms.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Postman on a Ubuntu 20.04 (Focal Fossa) server. You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

Step 2. Installing Snapd.
Snapd is the service that enables the installation and management of Snap packages. To install Snapd, open your terminal (Ctrl+Alt+T) and run the following command:
sudo apt update sudo apt install snapd
Step 3. Installing Postman on Ubuntu 20.04.
With Snapd installed, you can now install the Postman Snap package. Run the following command in your terminal:
