docker - 错误 : Service 'ubuntu' failed to build: The command '/bin/sh -c apt-get update

Question

当我执行命令 docker-compose up --build -d我收到这些错误:

E: Unable to locate package php7.4 E: Couldn't find any package byglob 'php7.4' E: Couldn't find any package by regex 'php7.4' E: Unableto locate package php7.4-fpm E: Couldn't find any package by glob'php7.4-fpm' E: Couldn't find any package by regex 'php7.4-fpm' ERROR:Service 'ubuntu' failed to build: The command '/bin/sh -c apt-getupdate && apt-get install -y curl zip unzip php7.4php7.4-fpm gettext-base sudo' returned a non-zero code:100

请问我的 dockerfile有什么问题吗？和 docker-compose.yml ?
这是我的 dockerfile

FROM  ubuntu:18.04

# ENV PORT=80
# ENV FPMSTREAM=9000

RUN apt-get update \
    && apt-get install -y curl zip unzip \
            php7.4 php7.4-fpm \
            gettext-base sudo



COPY ./webapp /var/www/webapp

WORKDIR /var/www/webapp

ADD default.conf /etc/nginx/conf.d/default.conf

RUN chown -R www-data:www-data /var/www && \
  chmod -R 775 /var/www && \
  useradd -m docker && echo "docker:docker" | chpasswd && \
  adduser docker sudo

您的问题是您正在尝试安装 Ubuntu 18.04 中不可用的 PHP 版本。

最新可用版本是7.2，所以需要替换php7.4 php7.4-fpm与 php php-fpm或 php7.2 php7.2-fpm
