I've created a EC2 instance in AWS with Ubuntu 18.04 bionic, and I'm connected with it using Putty Successfully.
But I only can see (use) the terminal and don't know how to deploy (either download or install) bionic desktop. I need it in order to install some programs in which graphical interface is required.
As you can see here it is possible. I don't use AWS, so I could not say if it is acceptable to have a server instance and install desktop packages and services to it.
I think, you should to ask Amazon support before installing any desktops to it.
Amazon guide gives the next instructions:
Note: These instructions apply only to Amazon Linux 2. To confirm which version you're running, run the command:
cat /etc/os-release
sudo amazon-linux-extras install mate-desktop1.x
sudo bash -c 'echo PREFERRED=/usr/bin/mate-session > /etc/sysconfig/desktop'
echo "/usr/bin/mate-session" > ~/.Xclients && chmod +x ~/.Xclients
sudo yum install tigervnc-server
vncpasswd
vncserver :1
sudo cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@.service
sudo sed -i 's/<USER>/ec2-user/' /etc/systemd/system/vncserver@.service
sudo systemctl daemon-reload
sudo systemctl enable vncserver@:1
sudo systemctl start vncserver@:1
Connect to the GUI using the VNC
Install the TigerVNC software on your local computer, if it's not already installed. TigerVNC is available for Linux, Windows, and macOS. See the TigerVNC website to access the download.
On your local computer, use SSH to connect to your instance while creating a tunnel to forward all traffic on local port 5901/TCP (VNC) to the instance's VNC server.
