Jetpack 3을 다운로드한 후 Jetson을 새로 고치고 CUDA 8을 설치해 보았습니다. 두 대의 다른 컴퓨터(WiFi 꺼짐)를 사용하여 설치를 시도했습니다. CUDA를 설치할 수 없습니다. 오류가 발생합니다. 두 컴퓨터 모두 설치 중 결함이 발생한 후 이더넷 연결이 더 이상 작동하지 않았습니다. 다른 컴퓨터에서 /etc/network/interfaces파일을 확인하고 비교했습니다 /etc/NetworkManager/NetworkManager.conf.
내 구성은 Ubuntu 16.04LTS, Jetson TX2, Jetpack 3입니다. 컴퓨터와 Jetson은 인터넷에 연결되는 허브에 연결됩니다.
현재 내 컴퓨터의 이더넷 연결을 복원하려고 합니다. 이제 내 컴퓨터가 DHCP 서버에 연결된 허브에 연결되었습니다. (Jetson TX2가 분리되어 있고 JetPack이 실행되고 있지 않습니다.)
문제를 찾기 위해 다음 명령을 시도했습니다.
$ ifconfig eth0(eth0에 연결하려고 할 때)
eth0 Link encap:Ethernet HWaddr 28:f1:0e:48:52:d2

IPV4 주소가 없으므로 DHCP가 요청을 받지 못했거나 보낼 수 없었다는 뜻인 것 같습니다.
$ 고양이 /etc/네트워크/인터페이스

좋아 보이네요. 저도 추가해 봤습니다
auto eth0
iface eth0 inet dhcp
나는 같은 결과를 얻었습니다.

나에게는 DHCP 서버에 요청을 보내는 데 실패했습니다. 그런데 일부 DHCP가 발견된 것 같습니다.
