Well after spending far-too-many hours on it I finally figured it out - the ends of my jumper wires weren't long enough. I'm surprised that was the case since they did go in about an inch, but I ended up just using a cut strand of some bare copper wire instead of a jumper and it worked great. Thanks for working with me for this longThe link for the pic still doesn’t work.
I don’t know enough of Linux, so I need to leave that to other experts.
