Stay connected to the internet so you can get the latest updates while you install Ubuntu. If you are not connected to the internet, you will be asked to select a wireless network, if available. We advise you to connect during the installation so we can ensure your machine is up to date

I started getting an error message when I log in Failed to Feb 11, 2019 pi 4 - RPi 4 running Ubuntu Server 20.04: can't connect to Boot Ubuntu Server, my RPi had no IP address (I switched to using a monitor when doing a headless setup failed, and calling hostname -I returns a blank line), which I believe is the result of having no internet connection, further demonstrated by sudo apt update failing with every line saying temporary failure resolving 'ports.ubuntu.com'. Cannot connect to internet (dns, vpn and popcorn time)
