如何卸载重装docker？

sudo docker -v

sudo apt-get remove docker

sudo apt-get remove --auto-remove docker

sudo apt-get remove --purge lxc-docker

sudo apt-get autoremove --purge

sudo apt-get install lxc-docker

sudo docker -v

如果想重新装最新版本：

sudo docker -v

sudo apt-get remove docker

sudo apt-get remove --auto-remove docker

sudo apt-get remove --purge lxc-docker
