How to Install Slack Messaging Tool in Linux

Slack is a modern, popular, feature-rich, flexible, and secure business communication and collaboration platform. It’s an enterprise-grade tool that ships with numerous features including channels, direct messaging, huddles and clips, and Slack connect for collaboration with external teams.

In slack, every message is indexed and therefore searchable, a workflow builder allows you to automate routine actions and communications, and file-sharing is supported.

Another key feature of Slack is its remarkable support for external services and custom apps. It supports integration with well-known services such as Google Drive, Dropbox, Office 365, Google Calendar, Twitter, Zoom, and 2200 others.

Besides, it supports 2-FA, Google SSO (Single Sing-On), SAML-based SSO(that gives members access to Slack through an identity provider (IDP) of your choice), and other security features.

For software developers and system administrators, Slack supports integration with DevOps and productivity tools such as GitLab, GitHub, Jenkins, Azure Pipelines, CircleCI, TravisCI, Nagios, Jira Cloud, Trello, and many more. You can also create custom apps and integrate your application with Slack.

Slack is available for free with limited features. To get more features, especially the advanced ones, you can upgrade to a paid plan.

You can either use Slack from a web browser (the web version), on mobile or install it on your Linux desktop as explained below.

  1. You don’t need to use dpkg. To install on Debian based systems you can just use apt:

    $ sudo apt ./slack-desktop-4.25.0-amd64.deb
