Thank you for the response. I got around to starting to need to use ROS on a Pi, but I encountered an error when trying to SSH into the machine.
I used the most recent Pi Image from the website you provided: 2020-11-07-ubiquity-xenial-lxde-raspberry-pi.img.xz
and I successfully used etcher to load it onto a microSD card.
The Pi I am using is Pi 3 Model B and it appeared to boot fine and created the wireless access point. I connected to the network, but then got an error. Please see the attached screenshot.
I got this error using the Pi’s name and also the ssh email@example.com
I then added the key “SHA256:Cw…AM” to the .ssh/known_hosts file, but still get the same error. Please let me know what I am doing wrong.
