어제 2개월 후에 Arch Linux를 업데이트했는데 sudo pacman -Syu다시 시작한 후에 브라우저나 Skype 등을 통해 인터넷에 연결할 수 없습니다.
google.com에 ping을 시도하면 다음과 같은 메시지가 나타납니다.
~]# ping google.com
ping: unkown host google.com
이더넷 연결을 확인할 때:
ip link
1: .....
2: enps2o: ... state UP ...
"ip addr"을 사용하면 여전히 일반 IP 주소가 있음을 알 수 있습니다.
dhcp 서비스를 다시 시작한 후, 우리 대학의 DHCP 서버에서 동일한 IP를 얻었지만 여전히 인터넷에 연결되지 않습니다. 그래서 새로운 이더넷 설정을 모두 살펴보겠습니다. 업데이트 후에 뭔가 문제가 있을 수도 있습니다.
이더넷 케이블을 뽑은 후 약 2초 동안 인터넷에 연결되었다가 연결이 끊어졌습니다.
이것은 요청된 변경 로그입니다. 죄송합니다. 마지막 업데이트가 7월 15일이었으니 불과 2주 전이군요 :)

그렇다면 커널에서 이 오류를 어떻게 해결할 수 있습니까? 이전 커널로 롤백을 시도했지만 작동하지 않았습니다. 뭔가 잘못한 것일까요?
답변1
이것은 커널의 버그인 것 같습니다.
업데이트된 모든 네트워크 패키지를 롤백하고 다운그레이드한 후 다시 작동합니다.
이것은 내가 사용하는 명령입니다:
[root@ulbp2681 ~]# cd /var/cache/pacman/pkg
[root@ulbp2681 pkg]# pacman -U linux-4.0.7-2-x86_64.pkg.tar.xz linux-headers-4.0.7-2-x86_64.pkg.tar.xz dhcpcd-6.9.0-1-x86_64.pkg.tar.xz netctl-1.10-2-any.pkg.tar.xz networkmanager-1.0.2-4-x86_64.pkg.tar.xz
해결책을 찾으려면 다음 두 가지 작업을 수행해야 합니다.
- Journalsctl -b는 현재 시작 후 시스템 로그에 사용됩니다.
- pacman-logfiles 업데이트 보기
