无法在Docker容器中安装ntopng（rfkill问题）
这是我得到的错误：
/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：

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

那么如何用rfkill解决这个问题呢？
它似乎试图运行udevadm作为其后安装的一部分。
从searchUbuntu的包看来， udev包提供了这一点。
你应该能够安装rfkill只要你事先安装udev 。
我能够得到这个docker文件来build立：
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
