How can I connect a Raspberry pi 4 running Ubuntu Server to a laptop?
fr flag

I am getting a Raspberry Pi 4. I want it to connect to my laptop wirelessly, without needing a hdmi cable, display or ethernet cable. I found a tutorial here that satisfies this, but it uses Raspbian rather than Ubuntu server, which is what I would like to install on it. Would this tutorial apply on Ubuntu server as well, or is there any other way to do this using Ubuntu Server?
