wget,从 16.04 升级到 17.10 后浏览器无法正常工作 - dnslookup 无法正常工作

编辑:

我的问题是我无法通过以太网连接互联网。当我运行 时wget http://google.com,我收到错误...failed: Name or service not known.Chrome 和 Firefox 无法加载任何网站,原因是连接问题。

当我插入其他计算机时,以太网工作正常。只有这台特定的机器不工作。

这显然是 DNS 查找问题。

我在另一台机器上找到了google.com的IP地址。

ping -c3 172.217.11.142 

ping 时间大约为 40 毫秒。

当我跑步时nslookup google.com,我得到;; connection timed ou; no servers could be reached

我尝试了解决方案这里这里使用 DHCP 和静态没有任何好处。

我首先尝试使用 DHCP,然后尝试使用静态

原始帖子

我昨晚从 16.04 升级到了 17.10。甚至在重启之前,以太网就停止工作了。当我进入网络管理器并单击“自动以太网”时,我看到弹出如下图像: 连接的

并立即断开连接,类似于此图 断开连接

我查阅了许多相关的帖子,但没有一个解决方案对我有用。

sudo nano /etc/NetworkManager/NetworkManager.conf

编辑为

[ifupdown] 管理=true

sudo service network-manager restart  #issue not resolved

显示我的托管/非托管连接

nmcli d

DEVICE TYPE STATE CONNECTION
enp0s25 ethernet connectd Wired connection 1
lo loopback unmanaged

sudo nano /etc/network/interfaces

编辑为

auto lo
iface lo inet loopback

重启网络管理器,仍然不起作用

ifconfig

(I'm having to manually type this, I'm skipping over addresses)

lsb_release -a确认我正在运行 17.10
