ubuntu - 无法构建任何 Dockerfile

Question

我对我的问题尝试了不同的答案，但似乎没有任何效果。
每当我尝试构建任何 docker 文件时，都会收到相同的错误消息:

E: Unable to locate package htop
INFO[0000] The command [/bin/sh -c apt-get install -y htop] returned a >non-zero code: 100

这是 Dockerfile:

FROM debian:latest
MAINTAINER <my_email>
RUN apt-get update
RUN apt-get install -y htop
RUN apt-get clean

我运行的命令是:

sudo docker build -t demo .

我也尝试了不同的软件包，但都有相同的错误。

我得到的是:

请帮我。

这就是我要做的 apt-get update在 ubuntu 的 docker 镜像中:

Err http://archive.ubuntu.com trusty-updates InRelease

以上Dockerfile你给了，为我工作。尝试再次获取中间层:docker build --no-cache=true -t <tag> .
使用的 Dockerfile:

FROM debian:latest

MAINTAINER user@email.com

RUN apt-get update && \
    apt-get install -y htop && \
    apt-get clean
