我尝试安装 MongoDB，但安装过程中出现问题，我想重新安装。不幸的是，我在尝试删除/清除时遇到错误，我怀疑这些错误可能与我随后重新安装失败有关。

我很困惑它是否已被完全删除，这就是为什么我收到这些错误，还是无法删除？如果是这样，那么 dpkg 是如何得出要删除的数字 62.2 Mb 的？我是否最好删除整个 Ubuntu 安装并从头开始？有没有关于在 Ubuntu 18.04 上安装 MongoDB 的好的、完整的指南？因为即使为了让我之前损坏的安装部分恢复，我也必须执行官方安装指南中未提及的线程中建议的操作。
编辑：明确的问题是我无法使用 apt-get purge mongo，而且服务甚至没有运行。

答案1
事实证明，/var/lib/dpkg/info 中有一些与 mongdb 相关的文件，一旦删除，清除就可以成功完成。我对 mongoDB 文档非常生气，因为它建议他们的软件包比操作系统存储库维护得更好，我应该从他们的存储库安装。
