Docker：Ubuntu上的Java 8安装失败

Question

我想在Docker容器中的Ubuntu的基本映像上安装java 8。 我运行下面的命令，

RUN apt-get update && \ 
apt-get install -y software-properties-common python-software-properties && \ 
add-apt-repository "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" && \ 
apt-get update && \ 
echo "$accept-license" | sudo debconf-set-selections && \ 
apt-get install --allow-unauthenticated -y oracle-java8-installer && \ 
rm -rf /var/lib/apt/lists/* && rm -rf /var/cache/oracle-jdk8-installer 

在运行上面的命令，我收到以下错误，

Connecting to download.oracle.com (download.oracle.com)|23.57.66.26|:80... connected. 
HTTP request sent, awaiting response... 404 Not Found 
2017-10-20 06:29:41 ERROR 404: Not Found. 

下载失败

Oracle JDK 8 is NOT installed. 
dpkg: error processing package oracle-java8-installer (--configure): 
subprocess installed post-installation script returned error exit status 1 
Errors were encountered while processing: 
oracle-java8-installer 
E: Sub-process /usr/bin/dpkg returned an error code (1) 

谢谢 尔汉

截至今天上午，Webupd8 Oracle-java8-installer已成功下载并安装在Docker中。 PPA安装程序中的链接必须已更新。好极了！

我Dockerfile这是在上周的最后失败，但现在工作

FROM ubuntu:14.04 

USER root 
RUN apt-get update 
RUN apt-get -y install default-jre 
RUN apt-get install -y software-properties-common python-software-properties 

RUN apt-get -y -q update && \ 
    apt-get -y -q upgrade && \ 
    apt-get -y -q install software-properties-common htop && \ 
    add-apt-repository ppa:webupd8team/java && \ 
    apt-get -y -q update && \ 
    echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections && \ 
    apt-get -y -q install oracle-java8-installer && \ 
    update-java-alternatives -s java-8-oracle

这是因为您使用的存储库可能不是e xisting。尝试另一个回购。
