3 Ways Installing Slack App in Ubuntu / Debian / Fedora & Other Linux

Want to install Slack client in your system? Here are the 3 ways that work on most Linux desktop systems.

Slack is a proprietary business communication platform that offers many IRC-style features, including persistent chat rooms organized by topic, private groups, and direct messaging.

Slack is available for Linux as native DEB and RPM, universal SNAP and FLATPAK packages.

1. Install Slack in Linux via native DEB / RPM:

The software offers official DEB and RPM packages (64-bit only) available for downloading at:

For Ubuntu, Debian, Linux Mint based systems, grab the DEB package, open terminal and install it via command:

sudo apt install /PATH/TO/DEB-PACKAGE

For Ubuntu, the command should be:

sudo apt install ./Downloads/slack-desktop*.deb

For Fedora based systems, grab the RPM package and install it via command:

sudo dnf install /PATH/TO/RPM-PACKAGE

(Optional) To remove slack in Ubuntu / Debian based systems, run command:

sudo apt remove slack-desktop

To remove slack in Fedora based systems, run command:

sudo dnf remove slack

Install Slack via SNAP in Linux:

SNAP is an universal Linux package format runs in sandbox. It’s developed by Canonical, the company behind Ubuntu.

Slack offers official snap package. For Ubuntu, you can simply search for and install it from Ubuntu Software:

For other Linux, first follow this guide to setup the Snap daemon. Then run command in terminal to install it:

sudo snap install slack --classic

(Optional) To remove the snap package, simply run command:

sudo snap remove slack

3. Install Slack via Flatpak package:

Slack is also available as the universal Flatpak package, which runs in sandbox and is maintained by the community.

First follow this guide to setup flatpak in Linux.

Then open terminal and install the client via command:

flatpak install flathub com.slack.Slack

(Optional) To remove the flatpak package, run command:

flatpak uninstall com.slack.Slack


While DEB / RPM are native system packages, both SNAP and FLATPAK run in sandbox for most Linux systems. You can choose one you prefer or install ALL of them alongside if you want.
