Hello, I’d messed around with my Jetson Nano for a while about six months ago, and it’s sat on a shelf for a bit. I got it back out, updated everything via apt, and now the included sample fails with a version tag. Does everything properly update via apt or do I need to use some other method to get the latest greatest? Here’s the full run:
