1. Install the desktop environment
Ubuntu servers are usually managed using the command line and don't have a desktop environment installed by default. Skip this step if you are running Ubuntu desktop.
There are many desktop environments for you to choose from in the Ubuntu source repositories. One option is to install Gnome, which is the default desktop environment for Ubuntu 20.04. Another option is to install xfce. It's fast, stable, and lightweight, making it an ideal desktop for remote servers.
Run any of the following commands to install the desktop environment of your choice:
Install Gnome
sudo apt update
sudo apt-get upgrade
sudo apt install ubuntu-desktopWhen installing ubuntu-desktop, select the first option
2. Install Xrdp
Xrdp is included in the default Ubuntu software repositories. To install it, run:
sudo apt install xrdpOnce the installation is complete, the Xrdp service will start automatically. You can verify it by typing the following command:
sudo systemctl status xrdpThe output will look like this:
● xrdp.service - xrdp daemon
Loaded: loaded (/lib/systemd/system/xrdp.service; enabled; vendor preset: enabled)
Active: active (running) since Fri 2020-05-22 17:36:16 UTC; 4min 41s ago

3. Use FinalShell to log in to the remote desktop
