How to Install Slack on Debian

Some organizations use a lot of collaboration tools which can affect internal communication and results in information being more scattered and unorganized. Slack is a team communication and collaboration application that allows you to centralize and organizes your workplace communication. It comprises instant messaging, voice and video calls, file sharing, and a set of tools to help teams communicate effectively. It is available for desktop (Linux, MacOS, Windows), mobile applications (iOS, Android), and web apps (Chrome, Edge, Firefox, Safari). In our previous posts, we described how to install Slack on Ubuntu and CentOS. In this post, we will describe how to install Slack on Debian Linux.

Slack is not available in the official repositories of Debian. So, you will have to get the package available on the Slack website.
