NOTE: Images, containers, volumes, and networks stored in /var/lib/docker/ are not automatically removed when you uninstall Docker.
To delete all images, containers, and volumes:
sudo rm -rf /var/lib/docker sudo rm -rf /var/lib/containerd
Remove source list and keyrings
sudo rm /etc/apt/sources.list.d/docker.list sudo rm /etc/apt/keyrings/docker.asc
NOTE: Any edited configuration files will need to be deleted manually.

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:

For more examples and ideas, visit:
https://docs.docker.com/get-started/
NOTE: This downloads a test image and runs it in a container.
sudo systemctl restart docker.service
sudo apt purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras
Then, manually remove the following two directories:
sudo rm -rf /var/lib/docker sudo rm -rf /var/lib/containerd
