Improve graphical installation instruction

[orschiro]

Dear all,

I am refering to the wiki wher eit says:

Graphical: Click here to install Gradio

However, this is not clear (at least to me). If I click the link on Linux Mint 18.3 Cinnamon, it downloads the .flatpakref file. If I open this file, it opens it inside a text editor. No way to install it graphically.

What else is needed and should be mentioned on the Wiki?

Currently I only know for sure this is supported by GNOME Software, so this needs to be available. KDE Discover made some progress with Flatpak support (including .flatpakref files), but I am not sure this is already readily available somewhere. At least in my KDE Neon VM it does not yet seem to work.

Related discussion might also be https://github.com/flatpak/flatpak/issues/859 , also the Flatpak team currently has no plans to implement a simple GUI themselves.

I tried an open with GNOME Software (3.20.5-0ubuntu0.16.04.7) right mouse click on the flatpakref file but only got this:

Just an update on KDE Discover: I tested again on my KDE Neon VM and it is fully working, you just have to install apt install plasma-discover-flatpak-backend.

@orschiro Given that Gnome Software 3.20 was AFAIK the first release supporting Flatpak I am not surprised. Flatpak support was bugged back then, but has matured very well and works quite good in latest version.

@phw good to hear. Wanted to test it but it is too difficult to install any version > 3.20 on Linux Mint 18.3 :-(

I've updated the introductions. Thanks for the information!
