How to remotely connect to Rasberry Pi 4?

Question

Raspberry Pi

Good time everyone.
I'm using Rasberry Pi 4, installed Ubuntu 20, latest.
Tell me how to set up an Internet connection to it.
I'm trying to activate the VNC interface when requested, raspy-config gives an error, this is through the terminal; I don’t understand through the graphical shell where the settings for the VNC server are, they write that VNC is installed in the latest builds, but I can’t find it.

Answer 1

in latest builds

in the latest builds of what? raspbian or ubuntu?

raspy-config

firstly, rasp i -config
secondly, this is a utility from raspbian, in unbuntu it, I suspect, no,
your question has nothing to do with raspberry. you have a regular linux (ubuntu) and want to connect to it - so google on this topic.
what I would use:
1. for everyday access - ssh, of course. if you need to run graphical applications on raspberry (why?) - yes ssh -X;
2. to access the desktop if you do not want it to be displayed on the display connected to the raspberry, then xserver-xspice. well, or vncserver, if you want exactly vnc.
3. if you need to watch exactly what is currently shown on the raspberry monitor, then x11spice or x11vnc, respectively.
