This repo hosts the Flathub Flatpak packaging for Tandem, available on Flathub.
Note that this packaging is unofficial and thus unsupported by Tandem. If you have issues, please verify that they occur when using an official packaging method before reporting them to Tandem. If you only can reproduce the issue with this Flathub Flatpak packaging, make an issue in this repository.
Tandem can be installed from Flathub like so, assuming you have Flathub set up:
$ flatpak install flathub chat.tandem.Client
$ flatpak run chat.tandem.Client
Looking at the log Tandem spews out when running in Flatpak, it by default says says this:
hostname: invalid option -- 'f'
Try 'hostname --help' for more information.
Using the hostname command (which is the only thing that gets built and
included) from inetutils solves this.
I couldn't figure out how to download a specific version of the deb/rpm, so I went with the Snap since they have a nice API for this.
