Flathub lists it as “Mattermost” (com.mattermost.Desktop), described as “An open source platform for developer collaboration”. The listing is not verified, so Mattermost has not confirmed it as its own package; Flathub shows “Mattermost, Inc.” as the developer name. It has been installed 135,512 times, number 61 of the 61 apps in our catalog that have a Flathub install count. Flathub flags its license as free software.
Linux Mint, Pop!_OS and Zorin OS have Flathub enabled out of the box, Fedora offers it as an optional third-party repository, and on Ubuntu you install Flatpak first.
Which install method should you use for Mattermost?
Use Flatpak unless you run Arch Linux: only Arch Linux packages it in our data, and Flatpak works on all of them.
- Mattermost’s own download. Mattermost publishes the Linux version itself on its website.
- Flatpak from Flathub. It is not a verified listing, so check that you trust its maintainer. It works the same on every distro, so it is the way to get one package everywhere.
- Your distro’s repositories. Arch Linux carries it in its own repositories, so a normal system update keeps it current. We found no package for Ubuntu, Debian, Fedora and openSUSE Tumbleweed.
