• 切换到root权限或者用sudo

• 升级source列表并保证https和ca证书成功安装

root@ubuntu-linux:~# apt-get updateroot@ubuntu-linux:~# apt-get install apt-transport-https ca-certificates

• 增加新的GPG 密钥

root@ubuntu-linux:~# apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

• 新增或编辑source列表里的docker.list文件

root@ubuntu-linux:~# vi /etc/apt/sources.list.d/docker.list  //如果不存在就新增# 删除已有的entriesdeb https://apt.dockerproject.org/repo ubuntu-xenial main

• 重新执行更新操作，并删除老的repo

root@ubuntu-linux:~# apt-get purge lxc-docker  //没有安装的话，跳过

• 查看是否有正确的可用版本

root@ubuntu-linux:~# apt-cache policy docker-enginedocker-engine:  Installed: (none)  Candidate: 17.05.0~ce-0~ubuntu-xenial  Version table:     17.05.0~ce-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     17.04.0~ce-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     17.03.1~ce-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     17.03.0~ce-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.13.1-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.13.0-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.12.6-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.12.5-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.12.4-0~ubuntu-xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.12.3-0~xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.12.2-0~xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.12.1-0~xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.12.0-0~xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.11.2-0~xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.11.1-0~xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages     1.11.0-0~xenial 500        500 https://apt.dockerproject.org/repo ubuntu-xenial/main amd64 Packages
