无法在WSL上从Ubuntu卸载Docker

Question

我正在尝试卸载Docker，但总是收到错误消息。我已经在互联网上进行搜索，但未能成功修复该错误。我印象中有一些破损的软件包，但对于Linux来说，我通常是新手。结果如下：

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

我希望有人能帮助我。:)

尝试从WSL中删除docker.io时，我也遇到了同样的错误，这显然是预先安装的。问题在于，由于Docker从未运行，因此删除前脚本失败，因此无法停止。

在我的情况下，我对/var/lib/dpkg/info/docker.io.prerm进行了sudo编辑，并将/sbin/stop docker其（失败）替换为true（仅返回成功）。在那之后，apt remove docker.io运行完美。

（我在这里找到了解决方案，这是2013年以来的一个老问题：如果从未使用过Docker，则无法将其卸载（Ubuntu））
