Now install packages pt-transport-https, software-properties-common and ca-certificates

sudo apt-get install apt-transport-https software-properties-common ca-certificates -y

Now get the gpg key

wget https://download.docker.com/linux/ubuntu/gpg && sudo apt-key add gpg

Add docker repository:

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

If the above step succeded, you are good to install docker

sudo apt-get install docker-ce -y
