None of the above worked for me.

I tried the following:

Code:

sudo apt install flatpak
flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.gnome.Platform/x86_64/47
flatpak install ~/Downloads/tangaracompanion-v0.4.3-linux-x86_64.flatpak

and the last command gives me the following error:

Code:

error: The application zone.cooltech.tangara.Companion/x86_64/stable requires the runtime org.gnome.Platform/x86_64/47 which was not found

If I run `flatpak install flathub org.gnome.Platform/x86_64/47` again I get:

Code:

Looking for matches…
Skipping: org.gnome.Platform/x86_64/47 is already installed

I've never used flatpak before so I'm probably missing something obvious - does anybody have any ideas?
