Hello,

From the aarch64 in the output, it looks like it's trying to install an ARM64 version, but this Flatpak doesn't work on ARM machines yet. I've actually got an arm machine in the last few days so I may go see about the viability of arm support.

Looks like since the base build is multiarch, flatpak-builder has no way of conditionally excluding packages causing the build to always fail: flatpak/flatpak-builder#381. So currently ARM support is not viable
