更新apt库安装包索引
sudo apt-get update
由于访问docker库需要使用https，需要安装https的依赖包
$sudo apt-get install \\ apt-transport-https \\ ca-certificates \\ curl \\ gunpg-agent \\ software-properties-common
添加docker的官方GPG公钥：
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
校验公钥是否添加成功，通过搜索公钥fingerprint后八位即可验证（9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88）：
$ sudo apt-key fingerprint 0EBFCD88
通过下面命令将stable(稳定版）docker库添加到本地apt仓库
$ sudo add-apt-repository \\ "deb [arch=amd64] https://download.docker.com/linux/ubuntu \\ $(lsb_release -cs) \\ stable"
更新本地仓库包索引：
sudo apt-get update
列出本地仓库可用的版本列表：
apt-cache madison docker-ce
执行安装： sudo apt-get install docker-ce=5:19.03.6~3-0~ubuntu-bionic docker-ce-cli=5:19.03.6~3-0~ubuntu-bionic containerd.io
报错，提示执行： sudo dpkg --configure -a
执行之：
执行Ok后继续安装：
