我正在尝试apt-utils在Docker 上安装,因为当我刚刚做的时候apt-get update,我收到了错误:debconf: delaying package configuration, since apt-utils is not installed.所以我添加了一行安装apt-utils(连同curl):
RUN apt-get update && apt-get install -y apt-utils && apt-get install -y curl
但是,我仍然遇到这个错误,导致我相信我的命令不起作用.当我尝试构建图像时,下面是我的输出.
Step 5/12 : RUN apt-get update && apt-get install -y apt-utils && apt-get install -y curl

造成这种情况的原因是什么？如何解决？谢谢!

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映像而没有任何apt-utils,无论这个警告消息如何,所有的软件包安装都会正常运行.
无论如何,如果你想要apt-utils - 安装它.它会给你一次这个警告,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,curl没有那条消息就安装了).
注意如果您安装apt-utils,您将收到其他警告(因为现在安装程序可以运行交互式配置并将尝试并失败).要取消这些并使包含具有默认值的交互式配置的包,请像这样运行apt-getDEBIAN_FRONTEND=noninteractive apt-get install -y pkgs....

搜索在互联网上后，我已经找到了一些替代品值得一提的，而不是每次投入时间DEBIAN_FRONTEND=noninteractive在前面apt-get install -y {your-pkgs}：
选择1：ARG DEBIAN_FRONTEND =非交互式
ARG指令定义了一个变量，用户可以在构建时使用--build-arg =标志使用docker build命令将其传递给构建器。（参考：[ 6 ]）
解决方案特点：
ARG 指令仅在构建期间设置docker build --build-arg DEBIAN_FRONTEND=newt例：
ARG DEBIAN_FRONTEND=noninteractive
...
RUN apt-get -yq install {your-pkgs}
选择2：即时
这是Leo K的解决方案。
解决方案特点：
RUN，不会影响其他指令。例：
RUN DEBIAN_FRONTEND=noninteractive apt-get -yq install {your-pkgs}
选择3：ENV DEBIAN_FRONTEND =非交互式
设置ENV DEBIAN_FRONTEND noninteractive也是一种替代方法，但是强烈建议不要这样做。
另一种方法是在乞讨处设置，在Dockerfile的末尾取消设置。
解决方案特点：
ENV 指令将在构建后保留环境变量（不推荐），此外ENV，它将被所有图像继承，并从图像中构建容器，从而有效地改变其行为。（如[ 1 ]中所述），以交互方式安装软件时，使用这些映像的人会遇到问题，因为安装程序不会显示任何对话框。DEBIAN_FRONTEND=newt（请参阅[ 2 ]，因此必须在文件末尾设置它。例：
# Set for all apt-get install, must be at the very beginning of the Dockerfile.
ENV DEBIAN_FRONTEND noninteractive
...
# Non-interactive modes get set back.
ENV DEBIAN_FRONTEND newt
备选方案4：RUN导出DEBIAN_FRONTEND =非交互式
解决方案特点：
RUN，不会影响其他指令。例：
# Set the frontend and then install your package
RUN export DEBIAN_FRONTEND=noninteractive && \
...
apt-get -yq install {your-pkgs} && \
...
