安裝openjdk-7-jre在Debian上「設置ca-certificates-java」時被阻止

Question

我試圖在docker-container中安裝jre，並使用 RUN apt-get install -y openjdk-7-jre在我的容器中安裝jre。當我開始建立它的過程受阻於這個命令：
Setting up ca-certificates-java (20140324)...

下面是截圖：screenshot

我dockerfile是Debian的：傑西：

COPY ./data /runtime/data 
RUN chmod 777 -R /runtime/data 
RUN apt-get update && \ 
    apt-get install -y openjdk-7-jre && \ 
    apt-get install -y screen && \ 
    rm -rf /var/lib/apt/lists/* 

Answer 1
