Hey @Vijay, Follow these steps:

Add the GPG key for the official Docker repository to your system:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Add the Docker repository to APT sources:

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
xenial \
stable"

Update your repositories:

$ sudo apt-get update

Install docker repo

$ apt-cache policy docker-ce

Finally, install docker

$ sudo apt-get install -y docker-ce

Start docker

$ sudo systemctl status docker

Check for docker version using the following command:

$ docker --version
