Question

我对我的问题尝试了不同的答案，但似乎没有任何效果。当我尝试构建任何docker文件时，我最终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 .

我尝试了不同的套餐，但都有同样的错误。

我得到的是：

请帮帮我。

这就是我在ubuntu的docker镜像中所做的apt-get update：

Answer 1

你给的上述Dockerfile，为我工作。尝试使用：docker build --no-cache=true -t <tag> .

再次获取中间层

使用Dockerfile：

FROM debian:latest

MAINTAINER user@email.com

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

Answer 2

怀疑，这是由于IPv6配置。请参阅here。

解决问题：

sudo nano /etc/default/docker
取消注释行DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
重新启动docker engine service docker restart

在Dockerfile中尝试使用它

FROM debian:latest MAINTAINER xx <xx@yy.com> RUN apt-get update && apt-get install -y htop && apt-get clean
