See my reply on this thread Re: RT demon is not running. rtapi_app_main(rtapi): -22 Invalid argument ??? for how to install an earlier package I would go back to machinekit_0.1.1532446277.git5d86a7e-1~stretch_armhf.deb and  machinekit-rt-preempt_0.1.1532446277.git5d86a7e-1~stretch_armhf.deb to be sure I think I know what it is, but won't have tome to fix until tomorrow On 14/09/18 15:41, Tac Huynh wrote: Please help: How do I fix this installation error?
