You have read and write permissions to the port. In some Linux distros, this is not the default setting. Under Ubuntu, you need to add your user to the dialout group:

sudo adduser $USER dialout
Then you must restart your PC for this to take effect and try again.

I haven't given up, my kid and his GF were here for a week, so I packed the scope up. In that time I installed Lubuntu on the RPI3 and even tried it on my laptop but I just didn't like it, so I went with Ubuntu Mate there. I was hoping to get out late, late tonight for some imaging but I'll probably stick with my windows setup for that At least I'll have the scope up and ready to tackle this fiasco again :)
