How to Install Slack on Ubuntu: 3-Minute Setup Guide 2025

Getting Slack up and running on Ubuntu is actually pretty straightforward, and I’ll walk you through the process as if we’re sitting down together to set it up. Let me share the most reliable methods I’ve used when helping teams transition to Slack on Linux.

Installing Slack via Ubuntu Software Center

The easiest way to get Slack on your Ubuntu system is through the Software Center – it’s like the App Store for Ubuntu. Just open the Software Center, search for “Slack,” and click install. The system handles all the technical bits for you, including future updates.

Using the Snap Store Method

If you’re comfortable with the terminal (don’t worry, it’s just one command), you can install Slack using Snap. Open your terminal and type:

“`
sudo snap install slack –classic
“`

The ‘–classic’ flag gives Slack the permissions it needs to work properly. I particularly like this method because Snap packages automatically update, keeping your Slack installation current without any extra effort on your part.

Downloading Directly from Slack

Here’s my preferred method when setting up Slack for teams – downloading directly from Slack’s website. Head to slack.com/downloads, grab the .deb package for Ubuntu, and then either:

1. Double-click the downloaded file to install through the Software Center
2. Use the terminal command:
“`
sudo dpkg -i slack-desktop-***.deb
“`
(Replace *** with the version number of your download)

Troubleshooting Common Installation Issues

Sometimes you might run into dependency issues, especially with the .deb method. If this happens, don’t panic! Just run:

“`
sudo apt –fix-broken install
“`

This command has saved me countless times when helping others with their Slack installations. It tells Ubuntu to fetch any missing pieces needed to make Slack work properly.

Post-Installation Setup

Once installed, you’ll find Slack in your applications menu. The first time you launch it, you’ll need to sign in to your workspace. Pro tip: If you’re using multiple workspaces, you can easily switch between them using Ctrl+1, Ctrl+2, etc., which I find incredibly helpful when managing different team communications.

Remember to check your system settings to configure notifications and startup behavior. I usually recommend setting Slack to start automatically on system boot for team members who need to stay connected throughout their workday.

Remember, whichever installation method you choose, Slack will keep your conversations synchronized across all your devices, just like on other platforms. The Linux version offers the same rich features as its Windows and macOS counterparts, so you won’t miss out on any functionality.
