How to Use Slack for Chromebook

There is no native ChromeOS app for Slack. If you searched for how to use Slack for Chromebook, that is why setup feels different from Mac or Windows. Slack supports Windows, macOS, iOS, Android, and Linux, but ChromeOS is not its own supported desktop platform. Slack on Chromebook works through a browser, a PWA, or Linux.

On many devices, Google Play shows “Slack isn’t available on Google Play on this device,” which makes the Slack Chromebook setup feel broken before you begin. Start with Chrome for quick access, install the PWA for daily use, or use Linux if you specifically want the desktop app.

Why There’s No Native Slack App for ChromeOS?

Slack publishes official apps for Windows, macOS, iOS, Android, and Linux. It does not publish a native ChromeOS app, so there is no direct Slack for Chromebook download like there is for Mac or Windows.

The Google Play Store can also be misleading. Some Chromebooks install Android apps, but Slack is blocked on many models and may show the “not available” message instead.

Note: If you searched for Slack plugin Chrome or a Slack Chrome extension, do not rely on that path. Slack’s old Chrome extension is not a current Slack-published install method. Use the web version, the PWA, or the Linux desktop app instead.

For Mac or Windows instructions, use Suptask’s guide on how to download Slack for desktop.

Which Install Method Should You Use?

Use this table before you start. It keeps the Chromebook Slack setup simple.

The web version works on almost every Chromebook that can open Chrome. The PWA is the right choice for most users because it gives Slack its own app window without Linux setup.

Method 1 - Use Slack in the Chrome Browser

This is the fastest way to use Slack on a Chromebook. It does not install anything, and it works even if your Chromebook is older or managed by a school or company.

1. Open Chrome on your Chromebook.
2. Go to app.slack.com. You can also go to slack.com and select Sign in.
3. Enter the email address linked to your Slack workspace.
4. Follow the email confirmation link or sign in with your workspace’s SSO provider.
5. Slack’s full web interface will load in the browser tab.

Tip: Right-click the Slack tab and choose Pin. The tab stays small and remains on the left side of Chrome.

Note: The web version handles messages, channels, file sharing, huddles, and calls. Use the PWA method below for better notification handling.

Method 2 - Install Slack as a Progressive Web App (PWA)

This is the recommended method for most Chromebook users. A PWA is the Slack web app installed through Chrome, so it opens in its own window and appears in your Chromebook launcher.

1. Open Chrome on your Chromebook.
2. Go to app.slack.com and sign in to your workspace.
3. Click the three-dot menu in the top-right corner of Chrome.
4. Select Cast, save, and share → Install page as app.
5. Confirm the name as Slack, then click Install.
6. Open Slack from your Chromebook launcher.
7. Right-click the Slack icon in the shelf and select Pin.

On older Chrome versions, the option may appear as More tools → Create shortcut. If you see Open as window, select it before creating the shortcut.

With the PWA, you get a standalone Slack window, a dedicated launcher icon, shelf pinning, and better notification handling than a regular browser tab.

Method 3 - Install Slack for Linux on Your Chromebook

Use this method if you want the Linux desktop version of Slack. This is not a native ChromeOS app; it runs inside ChromeOS’s Linux development environment.

Warning: Do not download a .DEB file and then run sudo snap install slack. That command is for Snap packages. For the .DEB flow below, the correct command is sudo dpkg -i.

Check Your Chromebook Supports Linux

Linux development environment requires ChromeOS 69 or newer. Most Chromebooks released in 2019 or later support it, but some older devices do not.

You should also have about 10 GB of free storage before enabling Linux. Some school-issued or company-issued Chromebooks have Linux disabled by an administrator.

1. Open Settings.
2. Go to About ChromeOS and check your ChromeOS version.
3. Go to About ChromeOS → Developers.
4. Look for Linux development environment.
5. If you see Set up or Turn on, your Chromebook supports Linux.
6. If the option is missing or grayed out, your device may not support Linux, or your admin has disabled it.

Note: If you use a managed Chromebook and cannot turn on Linux, contact your IT admin. The browser and PWA methods still work without Linux.

Enable the Linux Development Environment

1. Open Settings.
2. Go to About ChromeOS → Developers.
3. Next to Linux development environment, click Set up or Turn on.
4. Click Install in the setup dialog.
5. Leave the setup running until it finishes.
6. Open the Terminal app when it appears in your launcher.

Warning: Removing the Linux development environment later deletes Linux apps and files stored inside it. Back up anything important before removing it.

Install Slack via Terminal

Use Slack’s official Linux download page to get the current .DEB package. Do not use an old versioned Slack URL from another article.

1. Open Slack’s official Linux download page in Chrome.
2. Right-click Download .DEB app and copy the current download link.
3. Open the Terminal app from your Chromebook launcher.
4. Update the Linux package list:

sudo apt update

5. Download the current Slack .DEB package:

wget -O slack-desktop.deb "PASTE_CURRENT_DEB_LINK_HERE"

6. Install the downloaded package:

sudo dpkg -i slack-desktop.deb

7. If you see dependency errors, fix them with:

sudo apt --fix-broken install

8. Open your launcher and look for Slack in the Linux apps folder.

Important correction from the old install flow: sudo snap install slack is not how you install a downloaded .DEB file. The .DEB package must be installed with sudo dpkg -i slack-desktop.deb.

First Sign-In on Linux Slack

1. Launch Slack from the Linux apps folder.
2. Click Sign in to Slack.
3. Complete the sign-in flow if Slack opens it correctly.
4. If Slack says it cannot open a browser, open regular Chrome on ChromeOS.
5. Go to slack.com/signin and sign in to your workspace.
6. When Chrome asks whether to open Slack, choose Open in Slack.

Tip: After Slack opens, right-click the Slack icon in the shelf and select Pin.

Using the Android Slack App on Chromebook (Optional)

Some Chromebooks support Android apps through the Google Play Store. Where installation works, you can install the Android Slack app and sign in like you would on a phone.

For most Chromebook users, this is not the best option. The Android app uses a mobile layout on a laptop screen.

1. Open Google Play Store.
2. Search for Slack.
3. If Slack appears, click Install.
4. Open Slack and sign in.

Note: If Google Play says Slack is not available on your device, do not try to force it. Use the PWA or Linux method instead.

For phone setup, read Suptask’s guide on how to install Slack on mobile.

Common Issues Installing or Running Slack on Chromebook

1. “Slack isn’t available on Google Play on this device”

This is expected on many Chromebooks. Use Slack in Chrome, install the PWA, or use Linux.

2. Linux development environment will not enable

Your device may not support Linux, your ChromeOS version may be too old, or your administrator may have disabled it. Check Settings → About ChromeOS → Developers.

3. The .DEB file will not open from the Files app

Install it from Terminal instead. Move the file into Linux files, then run sudo dpkg -i slack-desktop-*.deb.

4. sudo dpkg -i returns dependency errors

Run:

sudo apt --fix-broken install

Then open Slack again from the Linux apps folder.

5. Slack sign-in fails on Linux

Linux may not have a default browser. Open slack.com/signin in regular Chrome, sign in, and choose Open in Slack.

6. No notifications in the PWA or web version

Open Chrome Settings → Privacy and security → Site settings → Notifications. Set Slack to Allow, then check Slack → Preferences → Notifications.

For more help, read Suptask’s guide on how to fix Slack notifications.

7. Audio or video calls do not work in Linux Slack

Linux Slack can be more fragile for media on ChromeOS. If you need reliable calls, use the PWA or web version.

8. The Slack app icon is missing after Linux install

Search the launcher for Slack. If it is not there, open the Linux apps folder and restart your Chromebook.

9. Slack keeps logging you out

For the PWA, clear Slack site data in Chrome. For Linux, download the current .DEB again and reinstall it with dpkg.

How Suptask Helps Teams Using Slack on Chromebooks

Slack works well for conversation, but recurring requests need structure. IT tickets, HR questions, support escalations, and internal service requests can get lost when they stay as loose channel messages.

Suptask turns Slack messages into trackable tickets directly inside Slack, with no separate Chromebook app to install. It works the same way whether your team uses Chromebook, Mac, or Windows, because Slack remains the interface.
