I am creating a Flatpak for my application. To learn the process with Gnome Builder I have used the start menu to pull "Music" which is listed as an example to try, but when I try to build it I get
"org.gnome.Sdk/x86_64/master not installed"
Gnome_builder attempt to download it but fails. I have tried "flatpak install org.gnome.Sdk/x86_64/master" but that fails too.
Update: Seems to have found it now.
