Install Slack on Debian 12, 11, or 10 via .deb Package

Step 1: Update Your Debian Before Slack Installation

Before starting the installation process, ensuring that your Debian Linux system is up to date is essential.

To update your system, run the following command:

sudo apt update && sudo apt upgrade

Step 2: Download Slack .deb Package on Debian

Now that your system is up to date, you need to download the Slack .deb package. First, go to the Slack downloads page and find the most recent download link for the Debian package.

Once you have the link, return to your terminal and use the wget command to download the package. Replace the example URL with the one you’ve obtained 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. Make sure to replace the version number with the one corresponding to the package you’ve downloaded.

Step 3: Install Slack on Debian via APT Command

With the Slack .deb package downloaded, you can now install it using the apt command. The following command installs 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 will install Slack and any required dependencies automatically.

Install Slack on Debian 12, 11, or 10 via Flatpak and Flathub

Flatpak is a powerful and versatile package management system with a sandboxed application environment. This means that applications installed with Flatpak run securely and independently from other applications and system libraries. This section will guide you through installing Slack using Flatpak and the Flathub repository.

If Flatpak isn’t installed on your system, please refer to the guide on how to install Flatpak on Debian for instructions on installing the latest supported version of Flatpak.

Step 1: Add the Flathub Repository on Debian For Slack

To install Slack using Flatpak, you must first add the Flathub repository containing the Slack package. To add the Flathub repository, open the terminal and enter the following command:

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

This command checks if the Flathub repository exists on your system and adds it if it’s not already present.

Step 2: Install Slack on Debian via Flatpak Command

With the Flathub repository added to your system, you can now install Slack. To do this, run the following command in the terminal:

flatpak install flathub com.slack.Slack -y

This command installs the Slack package from the Flathub repository in a sandboxed environment. The -y option automatically confirms the installation.

Upon completion of the installation process, Slack will be accessible on your Debian Linux system through the Flatpak sandboxed environment. This setup ensures Slack runs securely and independently from other applications and system libraries, providing enhanced security and stability for your team collaboration experience.
