答案1
您似乎有未配置的包（2 not fully installed or removed.）。
因此，您应该先通过执行 来处理这些问题sudo apt install -f。之后，您可以重试清除（sudo apt purge nginx）。根据您的情况，我建议使用 删除 nginx 子组件，以sudo apt autoremove --purge清除剩余的 nginx 依赖项，以便重新安装。
如果所有步骤成功，你可以重新安装 nginx（sudo apt install nginx）。
编辑：
由于问题无法通过这种方式解决，并且问题是由nginx-core您可以尝试通过以下步骤手动修复问题引起的：
sudo apt -f remove nginx-core
这告诉 aptF使用您提供的说明解决问题，即只需删除nginx-core。
编辑2：
由于最后一个失败的包是nginx-full（参见第 29 行你的日志）您也必须将其删除。
要做到这一点：sudo apt -f remove nginx-full
然后，按照上述步骤进行操作，从 开始sudo apt autoremove --purge。
