이더넷이 갑자기 작동을 멈췄습니다.

재부팅 후 이더넷이 작동을 멈추고 네트워크 위젯이 패널에서 사라졌습니다. Xubuntu의 라이브 부팅을 시도했는데 이더넷에는 문제가 없었습니다. 라우터도 다시 시작했습니다. 저는 XFCE를 사용하여 데비안 10을 실행하고 있습니다. 다음은 일부 출력입니다.

편집: dhclient -v enp3s0을 실행한 후 모든 것이 정상으로 돌아왔지만 재부팅할 때마다 실행해야 합니다. 연결 관리자를 수동으로 설치한 적이 없습니다.

기타 출력:

$ ls /etc/NetworkManager
dispatcher.d  NetworkManager.conf  system-connections

$ ls /etc/network/interfaces.d
