여러 오류로 인해 Hostapd를 시작할 수 없습니다

왜 그가 구성 파일을 찾을 수 없는지 모르겠습니다. 그는 ""를 검색하고 있는 것 같은데 아무것도 검색하지 않는 것 같습니다...! 저는 아무것도 편집하지 않았습니다...! 정상적으로 시작하려고 하면:

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.

"journalct1 -xe" 명령을 사용하면 다음과 같은 결과가 나타납니다.

# 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

# 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
