无法在Docker容器中安装ntopng (rfkill问题)

Question

下面是我得到的错误：

/var/lib/dpkg/info/rfkill.postinst: 5: /var/lib/dpkg/info/rfkill.postinst: udevadm: not found
dpkg: error processing package rfkill (--configure):
 subprocess installed post-installation script returned error exit status 127

和：

Setting up lsb-release (9.20160110ubuntu0.2) ...
Setting up dh-python (2.20151103ubuntu1.1) ...

Errors were encountered while processing:
 rfkill
E: Sub-process /usr/bin/dpkg returned an error code (1)

这是我的Dockerfile：

那么我该如何用rfkill解决这个问题呢？

Answer 1

它似乎正在尝试运行udevadm作为其安装后配置的一部分。

从searching ubuntu packages看来，udev包似乎提供了这一点。

只要事先安装了udev，就应该能够安装rfkill。

我能够得到这个dockerfile来构建：

FROM ubuntu:xenial

RUN apt-get update && \
    # Without this line, it did not build properly
    apt-get install -y --no-install-recommends udev && \
    apt-get install -y --no-install-recommends \
        rfkill && \
    apt-get clean
