在 18.10，我按照其文档安装 Docker CE。但我还没有成功完成。

有人有成功安装 Docker 的经验吗？
谢谢！
答案1
我做了同样的事情，没有出现任何问题，这意味着你一定缺少了某个步骤。尝试执行对我有用的下一组步骤：
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
sudo apt-get update
sudo apt-get install -y docker-ce=18.06.1~ce~3-0~ubuntu
sudo apt-mark hold docker-ce
sudo apt-mark hold docker-ce
使用此命令检查 Docker 包和 Docker cli 是否已安装：
dpkg -l | grep -i docker
预期输出：
ii docker-ce 5:19.03.6~3-0~ubuntu-xenial amd64 Docker: the open-source application container engine
ii docker-ce-cli 5:19.03.6~3-0~ubuntu-xenial amd64 Docker CLI: the open-source application container engine
最后检查版本：
docker version
