this is how i got MITM module to work 2.8.0
Open pineapple control center shut off any and all running procs wifi ,cron jobs,karma whatever, go to Advanced TAB and clear cache.
Next set up USB partition,make it primary EXT4 and a swap of 2 gig or more, now open USB TAB and under (config swap) change the 0 to a 1 then Update fstab. Now go to pineapple bar infusions MITM, install to USB wait for download to complete, now install the dependency's this is going to take a few mins so dont leave that page for anything,
It took me 30 mins that could be because im 1/4 mile away from neighbors AP
