由于多个错误，无法启动 Hostapd

尝试启动 Hostapd 时出现多个错误我将发布在尝试启动它并查看状态后得到的错误输出：

   root@l0calh0st:~# service hostapd status

我不知道为什么他没有找到他似乎在搜索的配置文件''又什么都没有......！我没有编辑任何东西......！在这里，如果我尝试正常启动它：

root@l0calh0st:~# service  hostapd start
Job for hostapd.service failed because the control process exited with error code.
See "systemctl status hostapd.service" and "journalctl -xe" for details.

如果使用命令“journalct1 -xe”我得到：

root@l0calh0st:~# journalctl -xe

编辑：好的，我找到了文件“hostapd.service”，但我没有看到任何注释掉的内容。（#？）：

[Unit]

这是 /etc/default/hostapd 文件：

# Defaults for hostapd initscript
#
# See /usr/share/doc/hostapd/README.Debian for information about alternative
# methods of managing hostapd.
#
# Uncomment and set DAEMON_CONF to the absolute path of a hostapd configuration
# file and hostapd will be started during system boot. An example configuration
# file can be found at /usr/share/doc/hostapd/examples/hostapd.conf.gz
#
#DAEMON_CONF=""

# Additional daemon options to be appended to hostapd command:-
#   -d   show more debug messages (-dd for even more)
#   -K   include key data in debug messages
#   -t   include timestamps in some debug messages
#
# Note that -B (daemon mode) and -P (pidfile) options are automatically
# configured by the init.d script and must not be added to DAEMON_OPTS.
