How to install Postman on Ubuntu

Postman is a powerful API development tool that helps you manage your APIs at every stage—from design and testing to documentation and monitoring. Originally launched as a Chrome browser plugin, Postman quickly became one of the most popular API tools used by developers worldwide. Today, it is available as a standalone native application (built on Electron) for all major operating systems, including Ubuntu, making it a go-to solution for API development.

Here we will learn the step-by-step process to install Postman on Ubuntu 20.04 using two popular methods: Snapcraft and Flathub

How to Install Postman on Ubuntu?

Postman may be installed in a variety of methods on Ubuntu. Let's take a look at each one individually.

Let's go through all the installation methods one by one.

Method 1: Using Snapcraft

Snapcraft is a universal package manager for Linux distributions that provides easy access to thousands of applications, including Postman.

Step 1: Install 'snapd' on Ubuntu

We may get Postman from the snapcraft shop using the 'snapd' tool, but first we must ensure that the snapd program is installed on Ubuntu; if it is not, run the command below to install it:

sudo apt install snapd

Step 2: Install Postman via Snapcraft

Then, using the snap package manager, download and install Postman:

sudo snap install postman

Method 2: Using Flathub

Flathub is another popular app store for Linux that utilizes the Flatpak package format. If you prefer using Flatpak, follow these steps:

Step 1: Install 'flatpak' on Ubuntu

Flathub, like snapcraft, is a Linux application store, therefore we can use the flatpak program to download and install postman from there. We'll use the apt package manager to install the flatpak utility.

sudo apt install flatpak

Step 2: Install Postman from Flathub

Using the flatpak program, download and install the postman package from flathub.

 flatpak install flathub com.getpostman.Postman

Step 3: Launch Postman

To launch Postman, navigate to the Application menu's search field, type "postman," and then click on the Postman application icon:

Now we successfully install Postman on our Ubuntu Operating System.

Troubleshooting Common Installation Issues

• If the Snap installation fails, try running 'sudo snap refresh' to update Snap and then reattempt the installation.
• If the system doesn’t recognize the 'flatpak' command, ensure it’s correctly installed by running 'sudo apt update && sudo apt install flatpak.'
• If Postman doesn’t launch after installation, check the permissions and ensure there are no conflicting dependencies.
