无法从WSL上的Ubuntu卸载Docker

Question

我正在尝试卸载Docker，但总是收到错误。我已经在互联网上搜索过了，但是没有成功修复这个错误。我的印象是有一些损坏的软件包，但总的来说我对Linux非常陌生。这就是结果：

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

我希望有人能帮我做这件事。:)
