How to Install Slack on Fedora 36 Linux

Slack is one of the most popular collaboration communication platforms in the world. Since it was initial launch in 2013, it has grown. It is now favored amongst development teams and corporations to integrate many services, run groups, meetings, etc. Slack works to create channels for your teams, topics, customers, or co-workers. Slack also features voice and video calls and file sharing when face-to-face meetings are impossible.

In the following tutorial, you will learn how to install Slack on Fedora 36 Linux using two different methods the DNF package manager utilizing a COPR repository or the natively installed third-party Flatpak package manager using the command line terminal.

Update Fedora Linux

The first step is to make sure your system is up-to-date to avoid issues during the installation and for good practice. This is done by opening your terminal and using the following command.

sudo dnf upgrade --refresh

Install Slack – DNF Method

Slack is not featured on Fedora’s default Appstream or the better-known RPM Fusion repository typically used to fill the void. However, a COPR repository exists that has been building Slack for a while.

First, enable the COPR repository from

sudo dnf copr enable jdoss/slack-repo

Once enabled, you need to install the Slack Repository with the following command; skipping this will cause issues, so do not ignore it.

sudo dnf install slack-repo -y

Once the Slack repository is installed, install the Slack Client using the following command.

sudo dnf install slack -y

Install Slack – Flatpak Method

The second option is to use the Flatpak package manager installed on Fedora-based systems. The extra benefit of using Flatpak installations is that you will always have the most up-to-date version. However, with distributions such as Fedora or similar types that focus on the latest packages, the significant advantage is often not as substantial or not present. However, still, this is the user’s discretion in choosing.

First, re-install the Flatpak manager if it was removed previously.

sudo dnf install flatpak -y

For users re-installing Flatpak, it is often recommended to reboot your system. Failure to do this can occur with odd issues arising, such as paths not being generated for icons.



Next, you need to enable Flatpack using the following command in your terminal.

sudo flatpak remote-add --if-not-exists flathub

Ideally, you should reboot at this stage; if you skip this and notice icons not appearing, the reboot will generate the paths required for the future.


Now install the video editor using the following flatpak command.

flatpak install flathub com.slack.Slack -y

If the above command does not work and you receive the “error: Unable to load summary from remote flathub: Can’t fetch summary from disabled remote ‘flathub’ use the following command.

flatpak remote-modify --enable flathub

This will fix the issue.

How to Launch Slack

Now that you have completed the installation launching, it can be done in a few ways.

Using the command line terminal, you can open the software quickly by using the following command.


Flatpak users will need to launch using the command below from a terminal instance.

flatpak run com.slack.Slack

The best way to use Slack for desktop users that prefer not to use the command line terminal is to open the GUI of the application by following the path.

Activities > Show Applications > Slack


When you open Slack, you can sign in or create a new workspace for users and teams new to the software.


Congratulations, you have installed Slack.

How to Update/Upgrade Slack

Depending on the method of installation used, the following commands can be used to update.

DNF Update Method

sudo dnf update --refresh

Flatpak Update Method

flatpak update

How to Remove (Uninstall) Slack

Use one of the following commands to suit the original installation method for users who no longer require the application.

DNF Remove Method

sudo dnf autoremove slack*

Once removed, if you no longer require Slack, you can disable the COPR repository where it was installed by using the following command.

sudo dnf copr disable jdoss/slack-repo

Flatpak Remove Method

flatpak uninstall --delete-data flathub com.slack.Slack

Next, run the following command for any leftover clean-up.

flatpak remove --unused

Comments and Conclusion

In the tutorial, you have learned how to utilize two different methods to install the Slack Client on Fedora 36 Linux using the command line terminal.

Overall, Slack is a great program, one of the drawbacks is the cost. Slack charges by the user, so If you get a few hundred to few thousand, it quickly becomes a drawback, hence why you only find corporations that use it and pay for a license. Most small businesses and development teams could not afford to pay for the premium features. However, it can still be used for free with relative ease if you accept missing out on a few things.
