I followed the steps to install docker on my EC2 instance which is based on Amazon AMI using the instructions from the official link - official docker installation on centos. I am getting the below error.
$ sudo yum update
........
$ sudo yum install docker-ce docker-ce-cli containerd.io

Where am I going wrong?

To get Docker running on the AWS AMI you should follow the steps below (these are all assuming you have ssh'd on to the EC2 instance). Add the ec2-user to the docker group so you can execute Docker commands without using sudo.
Install the most recent Docker Community Edition package. Start the Docker service. Add the ec2-user to the docker group so you can execute Docker commands without using sudo.
You can install Docker on an EC2 instance using the Amazon Linux 2 or Amazon Linux Operating System Migration Studio. Your instance should now communicate with your browser. Make sure the installed packages and cache are up to date in your instance. Make sure you have installed the most recent Docker Engine package.
@VikrantPawar yes. I have run the sudo yum update before installing docker No luck: sudo yum --nogpgcheck localinstall docker-ce docker-ce -cli containerd.io Loaded plugins: priorities, update-motd, upgrade-helper Skipping: docker-ce, filename does not end in .rpm. Skipping: docker-ce-cli, filename does not end in .rpm.
Solution in context of the image - Amazon Linux 2 AMI
One may need to remove the packages they installed using docker provided links
use the command here to remove all of that:-
sudo rm /etc/yum.repos.d/docker-ce.repo
And use the link given by AWS to install the docker here - https://docs.aws.amazon.com/AmazonECS/latest/developerguide/docker-basics.html
The content for that commands in that link are as below:-
Connect to your instance(Amazon Linux 2 AMI).
Update the installed packages and package cache on your instance.
sudo yum update -y
Install the most recent Docker Community Edition package.
sudo amazon-linux-extras install docker
Start the Docker service.
sudo service docker start
Add the ec2-user to the docker group so you can execute Docker commands without using sudo.
sudo usermod -a -G docker ec2-user
Log out and log back in again to pick up the new docker group permissions. You can accomplish this by closing your current SSH terminal window and reconnecting to your instance in a new one. Your new SSH session will have the appropriate docker group permissions.
Verify that the ec2-user can run Docker commands without sudo.
