Upgrade fails with Raspbian LXC
Just received my new Nano and attempting to get up and working with the provided Raspbian LXC template. I've given it 2 cores and 2GB RAM. Upon performing a standard upgrade command, I'm seeing the following...
pi@PiHole:~ $ sudo apt update
Hit:1 http://raspbian.raspberrypi.org/raspbian buster InRelease

I've also tried disabling/re-enabling it temporarily.
FWIW, this is the same response I receive on ANY newly deployed Raspbian LXC.
