I think this bug should be considered fixed, we no longer have a weird error message on non-supported images. That won't make non Debian/Ubuntu/whatever-supports-etc-network-interfaces magically work.
Not a big fan of throwing ImageUnacceptable exception if lsb_release is not Debian/Ubuntu: that could break images that support /e/n/i but overrided lsb_release.
Therefore I think this should be closed as a duplicate of 666554.
