Option to install qemu-utils instead of just displaying "Unsupported
On gnome-boxes (installed from deb as opposed to flatpak), if I run without qemu-utils installed and then try make a machine from an iso, I get a message something like "Unsupported Image".
In the console it says qemu-img is needed.
It would be great if gnome-boxes could use something like packagekit and offer to install qemu-utils (which provides qemu-img) in this case.
