在我的 Kubuntu 18.04 中，我安装了 docker-ce 并运行 LAMP 实例时遇到 python 找不到的错误：
$ docker-compose up -d --build

我注意到了消息：
since apt-utils is not installed
但是我已经安装了这个软件包：
$ dpkg --get-selections | grep apt-utils
apt-utils install
并在安装后重新启动了我的操作系统

可能是 docker 运行无效的 python 以及如何修复它吗？
$ lsb_release -d; uname -r; uname -i
Description: Ubuntu 18.04.3 LTS
4.15.0-20-generic
x86_64
$ docker -v
Docker version 19.03.2, build 6a30dfc
看起来容器中没有 Python。 尝试按如下方式修改
RUN apt-get update &&
apt-get install -y
python
在进行配置之前，它需要将python安装在容器中。
