1、备份配置文件：
sudo cp -a /etc/apt/sources.list /etc/apt/sources.list.bak
2、修改sources.list文件，将http://archive.ubuntu.com和http://security.ubuntu.com替换成https://mirrors.aliyun.com/，
可以参考如下命令：
sudo sed -i "s@http://.*archive.ubuntu.com@https://mirrors.aliyun.com/@g" /etc/apt/sources.list
sudo sed -i "s@http://.*security.ubuntu.com@https://mirrors.aliyun.com/@g" /etc/apt/sources.list
3、执行apt-get update更新索引
配置containerd安装源
1: 安装必要的一些系统工具
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
2: 信任 Docker 的 GPG 公钥
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
3: 写入软件源信息
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
4: 安装Docker
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
# 安装指定版本的Docker-CE:
1: 查找Docker-CE的版本:
apt-cache madison docker-ce
# docker-ce | 17.03.1~ce-0~ubuntu-xenial | https://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
# docker-ce | 17.03.0~ce-0~ubuntu-xenial | https://mirrors.aliyun.com/docker-ce/linux/ubuntu xenial/stable amd64 Packages
2: 安装指定版本的Docker-CE: (VERSION例如上面的17.03.1~ce-0~ubuntu-xenial)
apt-get -y install docker-ce=[VERSION]
