nanoPC-T4 在 # sudo apt update 和 sudo apt upgrade升级或安装软件 sudo apt install xxx时遇到以下问题：Failed to set up interface with /etc/hostapd/

【解决】
发现问题
Could not open configuration file '/etc/hostapd/hostapd.conf' for reading.

在目录下查看 hostapd.conf，发现没有该文件，当然无法打开配置文件了。

如何重新找到该文件
在目录 /usr/share/doc/hostapd 下可以看到有一个 README.Debian 文件, 文件内容如下：

hostapd for Debian
------------------

This package provides two methods for managing hostapd process(es); an
initscript and an ifupdown hook. Both methods require creation of a
hostapd daemon configuration file (eg. /etc/hostapd/hostapd.conf) to
function correctly.

An example hostapd.conf may be used as a template but _must_ be edited
to suit your local configuration. An example is located at:
  /usr/share/doc/hostapd/examples/hostapd.conf.gz

To use the example as a template:
  # zcat /usr/share/doc/hostapd/examples/hostapd.conf.gz > \
  	/etc/hostapd/hostapd.conf
  # $EDITOR /etc/hostapd/hostapd.conf

To use the initscript method of starting a hostapd daemon see
/etc/default/hostapd.

To use the ifupdown method, the path to hostapd configuration file can
be specified in a network interfaces configuration stanza in
/etc/network/interfaces like so:

iface eth1 inet static
	hostapd /etc/hostapd/hostapd.conf
	...

The hostapd process will be started in the pre-up phase of ifup, and be
terminated in the post-down phase of ifdown.

Please note:
* If you want to use hostapd with a Prism2/2.5/3 card in WPA mode, you'll need
  STA firmware version >= 1.7.0.
