E: Failed to fetch http://deb.debian.org/

可以使用国内163，阿里或者清华的源替换

#RUN sed -i s:/archive.ubuntu.com:/mirrors.aliyun.com/ubuntu:g /etc/apt/sources.list
RUN sed -i s:/archive.ubuntu.com:/mirrors.tuna.tsinghua.edu.cn/ubuntu:g /etc/apt/sources.list
RUN cat /etc/apt/sources.list
RUN apt-get clean
RUN apt-get -y update --fix-missing
