Thanks, Yaroslav. I don’t have overlays enabled, so didn’t get got by that gotcha. Another user (Bennet Fauber) explained that uname returns info on the host kernel. /etc/os-release shows that I am indeed in a Debian container, so that is good. It seems there are no neuro packages installed by default, I need to be doing a lot of apt-get. I found that my /etc/apt/sources.list needed updating for apt-get to be able to find packages. There could certainly be better instructions on getting this up and running!
