한동안 이 문제가 있어서 오늘 온라인에서 찾은 제안을 시도하고 실행하여 systemd-analyze plot결과를 확인했습니다.
여기에 SVG 파일을 첨부하는 이유는 제가 착각하지 않는 한 시작하는 데 시간이 오래 걸리는 일이 두 가지밖에 없기 때문입니다. 그 중 하나는 systemd-networkd-wait-online(물론) 그런데 이상하게 sendmail도 I조차 얻지 못합니다. 내 홈 네트워크 서버에서 시드박스/미디어 서버처럼 사용하고 있습니다.
여기서 뭔가 빠졌나요? wlan유선 기계이고 필요하지 않기 때문에 제외하기 위해 이전에 비활성화 했습니다 wlan.
비활성화하고 sendmail다시 시작하고 시간 초과를 확인한 다음 다시 실행했는데 이제 시간이 걸리는 유일한 것은 내가 고치려는 것뿐입니다. 어떤 도움이라도 대단히 감사하겠습니다.

나는 서비스를 비활성화함으로써 단순히 문제를 가리고 싶지 않습니다. 나는 renderer: networkd에서 로 변경하려고 시도했습니다 renderer: NetworkManager.netplan
추가, 출력하도록 설계됨networkctl
1 lo loopback carrier unmanaged
2 eno1 ether routable configured
3 wlp1s0 wlan off unmanaged
3 links listed.
그래서 거기에는 미친 것이 없습니다.
또한 optional: truenetplan에서 eno1을 구성했습니다.
편집: 아래에 지정된 대로 --any 및 --interface=eno1을 추가해 보았지만 둘 다 여전히 동일한 시간 초과를 갖습니다. https://ubuntuforums.org/showthread.php?t=2490962

가득한https://c0ld.net/dmesg.html여기에서 찾을 수 있습니다. 이제 무엇을 더 시도해야 할지 모르겠어서 인터넷을 통해 검색해 보았습니다.
eno1도 고정 IP로 구성되어 있으므로 사용 가능해지는 데 더 짧은 시간이 걸리는 대신 더 오래 걸리는 것은 의미가 없습니다.
192.168.2.1은 집 전체의 기본 라우터입니다. 여러 라우터와 수십 개의 장치가 있으며 다른 라우터에는 문제가 없습니다.

답변1
오 와, 알았어, 몇 가지 연습을 했고 미래의 여행자를 위해 NetworkManager와 netplan과 네트워킹의 혼란이 있습니다. 나는 가서 이 두 가지를 모두 따랐고(또는 어쨌든 약간의 비트가 누락되었음) 모든 것이 완벽하게 작동했으며 재부팅하는 데 몇 초밖에 걸리지 않았습니다. :)
