This article covers how to install and configure VNC Server on Ubuntu 20.04. Virtual Network Computing, or VNC, is a connection system that allows you to use your keyboard and mouse to interact with a graphical desktop environment on a remote server. It makes managing files, software, and settings on a remote server easier for users who are not yet comfortable with the command line.
After connecting to your server with SSH, update your list of packages:
$ sudo apt update
Now install Xfce along with the xfce4-goodies package, which contains a few enhancements for the desktop environment:
$ sudo apt install xfce4 xfce4-goodies
Once that installation completes, install the TightVNC server:
$ sudo apt install tightvncserver
