Docker debconf:延迟包配置，因为未安装apt utils

我正在设置Docker来运行我的CakePHP应用程序，我的Dockerfile如下

FROM php:7.2-apache

# Enable Apache Rewrite + Expires Module
RUN a2enmod rewrite expires

# Install dependencies
RUN apt-get update && apt-get install -y \
    unzip \
    libfreetype6-dev \
    libjpeg62-turbo-dev \
    libpng-dev \
    libyaml-dev \
    zlib1g-dev \
    libicu-dev \
    g++ \
    git \
    libzip-dev \
    zip \
    && docker-php-ext-install opcache \
    && docker-php-ext-configure intl \
    && docker-php-ext-install intl \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-configure zip --with-libzip \
    && docker-php-ext-install zip \
    && docker-php-ext-install -j$(nproc) gd \
    && docker-php-ext-install zip

但是当我跑的时候

docker-composer build

这给了我一个错误，比如

debconf: delaying package configuration, since apt-utils is not installed

日志就像

After this operation, 1607 kB of additional disk space will be used.

我尝试了GitHub问题和建议中指定的方法

RUN DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends apt-utils

而且

RUN apt-get update && apt-get install -y --no-install-recommends apt-utils

但是没有一个成功，错误仍然存在

进一步运行该进程会导致以下错误

这两个都不是错误——第一个可能可以忽略，第二个可能无法控制——实际的错误消息可能更深入（如果它根本无法构建）你的意思是我不应该担心这些错误？它们不是错误，它们是警告——是的，你不应该担心这些——它们超出了你的控制，不应该影响任何事情
