andrew  ~  flatpak build-update-repo
error: LOCATION must be specified

And then there is this...

 andrew  ~  flatpak install flathub org.ppsspp.PPSSPP
Looking for matches…
error: No remote refs found similar to ‘flathub’

Flatpak is installed, but I think there is some final step
Im supposed to take. Please help.

I tried running all the commands on that page, it seems the flathub repo contents
are not installed, so when I run a command to install a program, flatpak
says it does not know about said repo. Why is it so difficult to find a way to
add the repo......
