Docker:安装 apt-utils 时遇到问题

Question

我正在尝试在 Docker 上安装 apt-utils，因为当我刚刚执行 apt-get update 时，我收到了错误:debconf: delaying包配置，因为 apt-utils 没有安装。所以我添加了一行来安装apt-utils(连同curl):

RUN apt-get update && apt-get install -y apt-utils && apt-get install -y curl

但是，我仍然收到那个错误，让我相信我的命令不起作用。以下是我尝试构建图像时的输出。

这是什么原因造成的，我该如何解决？

Answer 1

这实际上不是一个错误，忽略它是安全的。我已经构建了大量的容器镜像，但没有在其中任何一个上安装过 apt-utils，并且无论此警告消息如何，所有软件包安装都通过并正常工作。

无论如何，如果你想拥有 apt-utils - 安装它。它会给你这个警告 once 然后它会在以后调用 apt-get 时消失(正如你在自己的日志中看到的那样，安装 curl 时没有该消息) .

注意，如果您安装了 apt-utils，您会收到其他警告(因为现在安装程序 可以 运行交互式配置，但会尝试这样做并失败)。要抑制这些并具有具有默认交互配置的软件包，请像这样运行 apt-get DEBIAN_FRONTEND=noninteractive apt-get install -y pkgs....
