How to Install Thunderbird Mail on AlmaLinux 9

Thunderbird Mail is a free, open-source e-mail client that can be used on your desktop computer and mobile devices like iPhone or Android. The mail client software was initially developed by the Mozilla Foundation but is now maintained by the Thunderbird community for the community.

In the following tutorial, you will learn how to install Thunderbird Mail on AlmaLinux 9 workstation desktop using one of two methods of installation: DNF or Flatpak package manager.

Update AlmaLinux 9

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 Thunderbird Mail – DNF Method

By default, Thunderbird Mail is available on AlmaLinux 9 appstream and is often up-to-date as Flatpak. Use the following command to install the mail application on your system.

sudo dnf install thunderbird -y

Alternatively, for users that prefer using Flatpak applications, the following method may be more preferred.

The second option is to use the Flatpak package manager that most often is natively installed on your AlmaLinux workstation. The benefit of Flatpaks is that they can often be ahead, sometimes far ahead, of AlmaLinux 9 appstream, depending on the release cycle/updates of the software and the Flatpak package maintainer.

First, re-install the Flatpak manager; this can be skipped if you already have it installed.

sudo dnf install flatpak -y

For users re-installing Flatpak for the first time, 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

Now install the mail client software using the following flatpak command.

flatpak install flathub org.mozilla.Thunderbird

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 Thunderbird Mail

Now that you have the application installed, launching can be done in a few ways.

For users with their terminal open, you can launch the application immediately using the following command.


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

flatpak run org.mozilla.Thunderbird

However, this is not practical, and you would use the following path on your desktop.

Activities > Show Applications > Thunderbird Mail.
