Question

我正在使用Dockerfile并且无法传递此错误。我已经研究了很多关于错误的内容，但似乎无法找到解决方案。

代码：
来自ubuntu：可信赖

RUN echo "deb http://www.apache.org/dist/cassandra/debian 36x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list  
RUN sudo apt-get install -y curl nginx  
RUN sudo apt-get update  
RUN curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -
RUN sudo apt-get update  
RUN sudo apt-get install cassandra  
RUN sudo service cassandra -fR

错误：...

E: Unable to locate package curl  
E: Unable to locate package nginx  
The command '/bin/sh -c sudo apt-get install -y curl nginx' returned a non-zero code: 100

即使我正在安装curl和nginx。请帮忙

在安装curl之前运行apt-get update。执行curl安装时，包列表不是最新的。此外，您必须让openjdk-8-jre-headless信任才能安装cassandra：

FROM ubuntu:trusty
RUN echo "deb http://www.apache.org/dist/cassandra/debian 36x main" | tee -a /etc/apt/sources.list.d/cassandra.sources.list
RUN apt-get update
RUN apt-get install -y software-properties-common && add-apt-repository ppa:openjdk-r/ppa -y && apt-get update
RUN apt-get install -y curl nginx
RUN curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add - && sudo apt-get update
RUN apt-get install -y cassandra
RUN service cassandra start

在Docker容器中运行Apache Cassandra
