无法在源文件中找到源链接，但仍显示在 apt 更新中

我是新手，我尝试在 18.04 中安装 MS SQL。但我遇到了一些问题，想删除与 MS SQL 相关的所有内容。

所以我purge删除了所有/etc/apt/sources.list与 Microsoft 相关的 GPG。

我还删除了从

curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add - 使用命令

sudo apt-key list和sudo apt-key del xxxxxx

现在当我这样做时，apt update我看到以下日志：

Hit:4 https://packages.microsoft.com/ubuntu/16.04/prod xenial InRelease        
Get:5 http://security.ubuntu.com/ubuntu bionic-security InRelease [88.7 kB]

W: Some index files failed to download. They have been ignored, or old ones used instead.

我不太清楚自己在做什么 :)。但我只想了解这里发生了什么，以及我现在应该做什么来删除它。

查看您的/etc/apt/sources.list.d/目录，看看是否有一些 Microsoft 源位于那里。此find查询也可能对您有帮助。

sudo find /etc/apt -name '*.list' -exec grep -i 'https://packages.microsoft.com' {} \; -print

这将返回包含字符串的文件https://packages.microsoft.com。
