(Yes, I’m aware of the existing Endless OS topic, but that one is closed, and not sure if conclusive.)
I intend to install Endless OS for a person completely unfamiliar with technicalities of an OS. Endless, while built from Debian, uses only OSTree + Flatpak to update itself, therefore the standard .deb packages won’t work.
Chrome can be installed on it, but Brave is obviously preferable, but not available.
Please consider creating a Flatpak option as well.
