How to Install Slack on Ubuntu 18.04

Slack is one of the most popular collaboration platforms in the world that brings all your communication together. Conversations in Slack are organized in channels. You can create channels for your teams, projects, topics, or any other purpose to keep information and conversations organized. You can search through everything that’s been posted in channels or your messages. Slack also allows you to talk with your teammates over audio or video calls and share documents, images, videos, and other files.

Slack is not an open-source application and it is not included in the Ubuntu repositories.

This tutorial explains how to install Slack on Ubuntu 18.04. The same instructions apply for Ubuntu 16.04 and any other Debian based distribution, including Debian, Kubuntu, Linux Mint and Elementary OS.

Prerequisites #

The user you are logged in as must have sudo privileges to be able to install packages.

Installing Slack on Ubuntu #

Perform the following steps to install Slack on Ubuntu.

1. Download Slack #

Open your terminal either by using the Ctrl+Alt+T keyboard shortcut or by clicking on the terminal icon.

Visit the Slack for Linux download page and download the latest Slack .deb package. You can also use the following wget command to download the package:

wget https://downloads.slack-edge.com/linux_releases/slack-desktop-4.0.2-amd64.deb

2. Install Slack #

Once the download is complete, install Slack by running the following command as a user with sudo privileges:

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

You may be prompted to enter your user password. Once you have correctly entered your password, the installation will continue.

3. Start Slack #

Now that you have Slack installed on your Ubuntu desktop, you can start it either from the command line by typing slack or by clicking on the Slack icon (Activities → Slack).

When you start Slack for the first time, a window like the following will appear:

From here, you can sign in to a workspace you are already a member of or create a new workspace and start collaborating with your friends and colleagues.

Updating Slack #

During the installation process, the official Slack repository will be added to your system. Use the cat command to verify the file contents:

cat /etc/apt/sources.list.d/slack.list
