Docker 构建失败：返回非零代码：1

Question

Dockerfile1

FROM ubuntu:latest
MAINTAINER ME
RUN apt-get update
RUN apt-get update && apt-get install -y net-tools \
&& apt-get install inetutils-traceroute \
&& apt-get install iputils-ping \
&& apt-get install xinetd telnetd

Dockerfile2

FROM ubuntu:latest
MAINTAINER ME
RUN apt-get update
RUN apt-get update && apt-get install -y net-tools
RUN apt-get update && apt-get install inetutils-traceroute
RUN apt-get update apt-get install iputils-ping
RUN apt-get install xinetd telnetd

Dockerfile3

FROM ubuntu:latest
MAINTAINER ME
RUN apt-get update
RUN apt-get install inetutils-traceroute
RUN apt-get install -y net-tools
RUN apt-get update apt-get install iputils-ping
RUN apt-get install xinetd telnetd

我尝试了 dockerfile 的所有上述风格，但每次都会遇到相同的错误：

The command '/bin/sh -c apt-get update && apt-get install -y net-tools && apt-get install inetutils-traceroute && apt-get install iputils-ping && apt-get install xinetd telnetd' returned a non-zero code: 1

有人发布了答案并在我接受之前将其删除。但这里是——

FROM ubuntu:latest
MAINTAINER ME

RUN apt-get update && apt-get install -y \
net-tools inetutils-traceroute \
iputils-ping xinetd telnetd

这有效！
