连接更新服务器 18.01.04.LTS 时出错

尽管 http/https 协议在机器上运行良好，但我无法连接到任何 ubuntu 服务器（尝试了几个）。

当我尝试使用软件更新程序进行更新时出现同样的错误。

我检查了这是否是名称服务器问题，但显然不是。当我 ping google DNS（4.4.4.4、4.4.4.8）时，我没有得到任何响应

我将非常感激听到任何建议.. :_(

我遇到了类似的问题，并通过以下方式解决了它：

  1. 我删除了文件 /etc/netplan/50-cloud-init^_copy.yaml。它就像变魔术一样出现在 netplan 文件夹中。它也可能是“麻烦制造者”。这始终列在提到的错误消息中。

  2. 然后我测试sudo netplan --debug apply并获得了正确的网络设置的系统调试配置。

以下是我的：

network: bonds: {} bridges: {} ethernets: enp3s0f0: addresses: - 192.168.178.122/24 dhcp4: false dhcp6: true gateway4: 192.168.178.1 nameservers: addresses: - 192.168.178.33 - 192.168.178.1 optional: true enp3s0f1: addresses: - 192.168.178.123/24 dhcp4: false dhcp6: true gateway4: 192.168.178.1 nameservers: addresses: - 192.168.178.33 - 192.168.178.1 optional: true enp4s0f0: addresses: - 192.168.178.124/24 dhcp4: false dhcp6: true gateway4: 192.168.178.33 nameservers: addresses: - 192.168.178.33 - 192.168.178.1 optional: true enp4s0f1: addresses: - 192.168.178.125/24 dhcp4: false dhcp6: true gateway4: 192.168.178.33 nameservers: addresses: - 192.168.178.33 - 192.168.178.1 optional: true vlans: {} wifis: {}

  1. 这个配置我放入了原来的50-cloud-init-yaml中，并保存了下来。

  2. sudo netplan apply我重新启动了 netplan。它向sudo ifconfig我显示了正确的配置，并且我获得了 apt 的互联网连接等等。
