无法在泊坞窗容器安装ntopng（rfkill问题）

问题描述：

/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

这里是我的Dockerfile：

那么我如何用rfkill解决这个问题？

答

它似乎试图运行udevadm作为其后安装的一部分。

从searching ubuntu packages看来，udev包提供了这一点。

您应该只要您事先安装udev就能够安装rfkill。

我能得到这个dockerfile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
