docker - 无法在 WSL 上从 Ubuntu 卸载 Docker

Question

我尝试卸载 Docker，但总是收到错误消息。我已经在互联网上搜索过，但没有成功修复该错误。我的印象是有一些损坏的软件包，但总的来说我对 Linux 很陌生。这是结果:

sudo apt-get purge -y docker-ce 
                                                                                                                                                 1 ↵ Reading package lists... Done

我希望任何人都可以帮助我。 :)

我在尝试从 WSL 中删除 docker.io 时遇到了同样的错误，它显然是预安装的。问题是预删除脚本失败，因为 docker 从未运行过，因此无法停止。

就我而言，我对/var/lib/dpkg/info/docker.io.prerm 进行了 sudo 编辑，并将 /sbin/stop docker (失败)替换为 true (仅返回成功)。之后， apt remove docker.io 完美运行。

(我在这里找到了解决方案，2013年的老问题:docker can't be uninstalled if it never worked (Ubuntu))
