Debian Stretch 升级：卸载 docker 云，仍在 apt 列表中

Question

几个月前我曾尝试安装 docker 云，但我删除了它。现在我已经从 Jessie 更新到 Debian Stretch，当我通过 "apt-get update" 更新时我收到这个错误并且不知道如何解决它。谁能提供一些帮助？谢谢！

实际上这是一个警告而不是错误。似乎在您的 SourcesList 中的某处（例如 /etc/apt/sources.list）您仍然有一个 docker 回购协议。

$ sudo grep -w "docker.com" /etc/apt/*.*

将显示 docker 的 url 在哪里。如果您不再需要它，只需将此行注释掉即可。

嗯，如果您还需要 docker，这个 link 可能会有帮助。
