本文档详细介绍了如何卸载旧版本的Docker，并通过DEB包安装Docker CE。此外，还提供了创建docker组及添加用户的步骤，确保用户能够无须使用sudo即可运行docker命令。

Older versions of Docker were called docker or docker-engine. If these are installed, uninstall them:

执行命令：sudo apt-get remove docker docker-engine docker.io

Install Docker CE, changing the path below to the path where you downloaded the Docker package.
```
$ sudo dpkg -i /path/to/package.deb
```
The Docker daemon starts automatically.
Verify that Docker CE is installed correctly by running the hello-world image.
```
$ sudo docker run hello-world
```

To create the docker group and add your user:

Create the docker group
```
$ sudo groupadd docker
```
Add your user to the docker group
```
$ sudo usermod -aG docker $USER
```
Log out and log back in so that your group membership is re-evaluated.
If testing on a virtual machine, it may be necessary to restart the virtual machine for changes to take effect.
On a desktop Linux environment such as X Windows, log out of your session completely and then log back in.
Verify that you can run docker commands without sudo
```
$ docker run hello-world
```
