我在Bash中运行以下命令：
DEBIAN_FRONTEND=noninteractive apt-get update -qq \
&& apt-get install -y build-essential git libncurses5-dev openssl \
libssl-dev fop xsltproc unixodbc-dev curl
它运行，但在中间失败：

因此整个操作失败并显示错误

我将其作为Docker构建的一部分进行运行。我的Dockerfile读取
FROM debian:jessie
RUN DEBIAN_FRONTEND=noninteractive \
apt-get update -qq \
&& apt-get install -y \
build-essential \
git \
libncurses5-dev \
openssl \
libssl-dev \
fop \
xsltproc \
unixodbc-dev \
curl
而我正在跑步 docker build -t my-base:latest .
该apt-get命令有时会成功执行，而有时会失败而无需更改任何内容。在本地开发计算机上运行它似乎总是成功，但是在EC2计算机上运行它却经常（但并非总是！）失败。此外，apt-get update在apt-get install帮助之前似乎连续运行两次。不过，我对最后两句话完全不满意。
任何想法可能会发生什么？apt-get中是否可以缓存某个时间戳，然后期望它是最新的？
