我已经安装并配置了 priunl vpn 客户端，就像我在另一台 Ubuntu 16.04 机器上所做的那样。在我建立连接后大约 15 秒，它被终止，我不明白为什么。

到目前为止我已经尝试过：
- 在网络管理器配置中将 tun0 接口标记为非托管
- 停止网络管理器
- 通过添加 -L 参数强制 ntpd 忽略虚拟接口
到目前为止没有任何效果。
更新 删除网络管理器会完全破坏 cinnamon，因此这不是一个选项，但是我将 NM 的日志级别增加到 DEBUG

答案1
虽然不是问题的解决方案，但我设法使用本地 openvpn 客户端和提供商的配置文件使 VPN 正常工作
看来网络管理员只是不喜欢 Pritunl 客户端建立的连接
