我尝试将 Docker 安装到 Ubuntu 18.04。
我使用这个指南： https://docs.docker.com/install/linux/docker-ce/ubuntu/
第一次，我通过了所有步骤，但在最后尝试安装 docker-ce 时出现错误：
# apt-get install docker-ce docker-ce-cli containerd.io
然后，安装就出错了。之后，我尝试从第一步再次安装 docker：
$ sudo apt-get remove docker docker-engine docker.io containerd runc
并得到这个：

请帮助我解决问题并安装docker。

我遇到了类似的问题。Ubuntu 从 18.04.4 升级到 20.04.2 后，docker 无法启动，并且在尝试安装、删除、清除、修复时出错。

有两个可以安装的 docker 软件包：来自 Debian/Ubuntu 的 docker.io 和来自 docker.com 的 docker-ce。这邮政讨论差异。我都安装了
dpkg -l | grep -i docker
看起来它被卡住了，containerd无法启动。您可以在/var/log/syslog
尝试了很多方法，但都没有用
$ sudo dpkg --configure -a
$ sudo systemctl list-jobs
$ sudo systemctl disable docker.service
$ sudo systemctl disable containerd.service
$ sudo systemctl stop containerd.service
...
删除文件夹，卸载所有 docker 软件包并重新安装 docker.io 有效
$ sudo rm -rf /var/lib/containerd/
$ sudo rm -rf /var/lib/docker/
$ sudo apt-get purge -y docker-ce docker-ce-cli docker.io containerd.io
$ sudo apt-get install docker.io
