nodejs安装使用ubuntu基本映像但不使用consol / ubuntu-xfce-vnc

Question

我正在尝试使用consol/centos-xfce-vnc来运行自动化脚本。因此我想安装nodejs。令我惊讶的是，当尝试使用ubuntu时，它确实有效，但不适用于ubuntu-xfce-vnc。

工作Dockerfile

# Pull base image.
FROM ubuntu:14.04

# Install Node.js
RUN apt-get update && apt-get install -y \
curl
CMD /bin/bash

RUN curl --silent --location https://deb.nodesource.com/setup_4.x | sudo bash -
RUN apt-get install --yes nodejs
RUN apt-get install --yes build-essential

RUN which node; node -v; which npm; npm -v;

不工作Dockerfile

# Pull base image.
FROM consol/ubuntu-xfce-vnc:1.1.0

# Install Node.js
RUN apt-get update && apt-get install -y \
curl
CMD /bin/bash

RUN curl --silent --location https://deb.nodesource.com/setup_4.x | sudo bash -
RUN apt-get install --yes nodejs
RUN apt-get install --yes build-essential

RUN which node; node -v; which npm; npm -v;

我收到以下错误

Step 2/7 : RUN apt-get update && apt-get install -y curl
