Installation

sudo apt install -y flatpak

Extra steps:

Install the GNOME Software plugin, but not working since 20.04 due to it being a distributed as a snap, so will install an additional software package instead:

sudo apt install gnome-software-plugin-flatpak

Add the flatpak repository:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

A restart may be required due to XDG_DATA_DIRS environment variable not containing the new path(s) yet.

Flatpak maintainers seems to not like the $XDG_CONFIG_HOME as per Config.yaml file location amiguity #111. Here is to hoping that it is just some miscommunication and that it will be sorted in the future.

Search for applications with flatpak search halloy or visit Flathub to look for software and instructions on how to install them.

Make sure to always keep your Operating System(s) and all of the software that you are using up to date.
