本文详细介绍如何在Ubuntu系统上卸载旧版本Docker、安装最新版本并进行配置，包括设置国内镜像源、创建及加入Docker用户组等关键步骤。

保证
1. 卸载旧版本

`sudo apt remove dokcer` 
`sudo apt remove docker.io`
`sudo apt remove docker-engine`

2. 更新apt库

`sudo apt-get update`

安装允许HTTPS使用存储包

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
添加官方GPG密钥

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

鉴于国内网络问题,更换为国内源

curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

搜索指纹对吼8个字符确认

sudo apt-key fingerprint XXXXXXXX
向source.list添加Docker软件源

$ sudo add-apt-repository "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
安装Docker CE

sudo apt-get update

sudo apt-get install docker-ce

或使用脚本安装

curl -fsSL get.docker.com -o get-docker.sh

sudo sh get-docker.sh --mirror Aliyun
启动docker

sudo systemctl enable docker

sudo systemctl start docker
建立docker用户组
1. 建立组
  
  sudo groupadd docker
2. 将当前用户加入docker组
  
  sudo usermod -aG docker $USER
3. 退出终端并重新登录
测试

docker run hello-world

正确信息显示如下:

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
ca4f61b1923c: Pull complete
Digest: sha256:be0cd392e45be79ffeffa6b05338b98ebb16c87b255f48e297ec7f98e123905c
Status: Downloaded newer image for hello-world:latest

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
