我刚刚在一台新台式电脑上安装了全新的 Ubuntu 16.04 LTS,它无法通过有线连接连接到互联网。
我见过几个类似问题的答案,例如:
为什么有线互联网在 Ubuntu 16.04 LTS 中无法工作?
还有其他几个,但他们提出的解决方案都不适合我。我有一块华硕 Z270 主板,标准诊断的输出是:

希望您能帮助我解释为什么无法连接...谢谢!
答案1
我在解决其他问题时发现了一个解决问题的方法——安装 Ubuntu 16.10 就可以了。
我看到对于另一款计算机型号 Intel NUC,建议使用 Ubuntu 16.10,因为 16.04 对 Kaby Lake CPU 的支持不太好:
https://communities.intel.com/thread/114411
http://nucblog.net/2017/04/kaby-lake-i7-nuc-conclusions/
所以我检查了一下,这台电脑也有 Kaby Lake 系列的 i7 7700K,即与 Ubuntu 16.04 配合不佳。
安装了 16.10 并且一切正常。
谢谢您的帮助 :)

I219-V Intel 以太网控制器有多个版本。楼主肯定用的是较早的版本。Ubuntu 16.10 不支持较新的版本。适用于所有版本的控制器的解决方案如下英特尔的 e1000e 基础驱动程序说明。在这种情况下您可以继续运行 16.04 LTS 版本。
英特尔说明书没有说明安装制作和海湾合作委员会。我遵循的步骤如下:
# Download e1000e tar file from https://downloadcenter.intel.com/download/15817
sudo apt install make gcc
tar xvfz e1000e-*.tar.gz
cd e1000e-*/src
sudo make install
sudo rmmod e1000e # It's ok if this has an error
sudo modprobe e1000e
如果此操作有效,那么您将在 /var/log/kern.log 末尾看到设置相关以太网接口的消息,并且新接口将列出,
