我有一台 Vagrant 支持的 Ubuntu VM，我想在上面做一些性能测试。为了做到这一点，我尝试安装 gdb
当我运行 apt-get install 时，我看到以下内容：
vagrant@ubuntu-1204:~$ sudo apt-get install gdb
sudo: /etc/sudoers.d/vagrant is mode 0644, should be 0440

据我所知，缺少一些网络配置，但我有点不知所措。我可以 ping google.com 并得到成功的响应，所以我有点困惑为什么 security.ubuntu.com 似乎在 192.168.0.0 上
这是我所看到的ifconfig

任何帮助将非常感激！
更新
尝试添加
config.vm.network "public_network", bridge: [
"en0: Wi-Fi",
"en3: Thunderbolt"
]
但问题仍然存在。
这是路由表：

10.9.100.0 * 255.255.255.0 U 0 0 0 eth1
我也尝试 ping Ubuntu 服务器，结果一切正常：

答案1
Vagrant 使用 VirtualBox。因此，请转到您的实例并检查您的网卡是否正确桥接。您可以在 Vagrantfile 中配置它。例如，我的 Macbook 的线路用于将网络桥接到我的 WLAN 卡。
server.vm.network "public_network", bridge:'en0: WLAN (AirPort)'
也许这对您的问题有帮助。
http://docs.vagrantup.com/v2/networking/public_network.html
检查你的 VBox 设置。是否有正确的网络桥接。
您是否设置了另一个网关？也许创建一个新实例并检查它是否正常工作。也许您的包管理器中存在任何错误配置。
答案2
奇怪的是 apt-get 正在连接 192.168.0.0:59875。
您对 apt-get 使用了代理吗？
检查一下：
$ apt-config dump Acquire::http::Proxy
$ echo $http_proxy
