Now, onto the below to start with this tool on your Ubuntu system. This guide demonstrates how to install Slack on Ubuntu 22.04 Jammy Jellyfish or Ubuntu 20.04 Focal Fossa through direct download, Flatpak from Flathub, and Snapcraft.

Install Slack on Ubuntu 22.04 or 20.04 via .deb

Step 1: Update Ubuntu Before Slack Installation

To ensure a smooth installation process and maintain good practice, keeping your system up-to-date is crucial. This helps avoid potential issues during the installation process. Open your terminal and execute the following command to update your Ubuntu system:

sudo apt update && sudo apt upgrade

This command updates the package list and upgrades installed packages to their latest versions.

Step 2: Download the Slack .deb Package on Ubuntu

After updating your system, proceed to download the Slack .deb package. First, visit the Slack downloads page and locate the most recent download link for the Debian package.

Once you’ve obtained the link, return to your terminal and use the wget command to download the package. Replace the example URL with the one you acquired from the Slack downloads page:

wget https://downloads.slack-edge.com/releases/linux/4.31.155/prod/x64/slack-desktop-4.31.155-amd64.deb

In this example, we’re using Slack version 4.31.155. Ensure to replace the version number with the one corresponding to the package you’ve downloaded.

Step 3: Install Slack on Ubuntu 22.04 or 20.04 via APT Command

With the Slack .deb package downloaded, you can now install it using the apt command. Execute the following command to install Slack on your system:

sudo apt install ./slack-desktop-4.31.155-amd64.deb 

Remember to replace slack-desktop-4.31.155-amd64.deb with the filename of the package you’ve downloaded. This command installs Slack and any required dependencies automatically, making the process seamless and efficient.

Install Slack on Ubuntu 22.04 or 20.04 via Flatpak and Flathub

This second method explores an alternative way to install Slack using the Flatpak package manager. Flatpak is a universal package management system, similar to Snap, that allows you to install and manage applications in a secure and isolated environment. It offers benefits such as easy updates, sandboxing, and cross-distribution compatibility.

Step 1: Enable Flathub For Slack on Ubuntu

Before installing Slack through Flatpak, you must enable the Flathub repository, a primary source for Flatpak applications. To enable Flathub, execute the following command in your terminal:

sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

This command adds the Flathub repository to your Flatpak configuration, ensuring you have access to various applications, including Slack.

Step 2: Install Slack on Ubuntu 22.04 or 20.04 via Flatpak Command

With Flathub enabled, you can now install Slack using the flatpak install command. Run the following command in your terminal:

flatpak install flathub com.slack.Slack -y

This command installs Slack from the Flathub repository, providing you with the latest version of the application.

If your system does not have Flatpak installed, please refer to our guide on How to Install Flatpak on Ubuntu for step-by-step instructions on installing the most recent supported version of Flatpak.

Install Slack on Ubuntu 22.04 or 20.04 via Snapcraft

We’ll install Slack through the Snapcraft package manager in this third method. Snapcraft, a universal package manager, emphasizes simplicity, security, and compatibility with various Linux distributions. Ubuntu systems already have Snapcraft, so installing applications like Slack is convenient.

Step 1: Install Snap Core on Ubuntu

The first step is to install the Snap Core on your system. Snap Core is a fundamental component that provides the runtime environment for snaps. To install Snap Core, execute the following command in your terminal:

sudo snap install core

This command installs the Snap Core, ensuring your system is ready to manage Snap packages.

Step 2: Install Slack on Ubuntu 22.04 or 20.04 via Snap Command

With Snap Core, you can install Slack using the Snapcraft package manager. Run the following command in your terminal:

sudo snap install slack --classic
