2.Remove older versions of docker
Older versions of Docker were called docker, docker.io, or docker-engine. If these are installed, uninstall them:
user@computer$ sudo apt-get remove docker docker-engine docker.io containerd runc
3. Set Up Repository.
user@computer$ apt-get update
user@computer$ apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
4. Add Docker’s official GPG key:
user@computer$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
5. Verify that you now have the key with the fingerprint
user@computer$ apt-key fingerprint 0EBFCD88
and output should be like below
pub rsa4096 2017-02-22 [SCEA]
9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88

6. Use the following command to set up the stable repository.
user@computer$ add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
and output should be like below
