我正在尝试设置 WireGuard VPN。我已经设置了接口和客户端。但是当我运行时sudo wg，尽管看到了接口和对等信息，但数据只发送了而没有接收，所以我没有握手。这可能是什么原因？我有点犹豫，不知道我是否输入了正确的端点地址和允许的 IP 地址。
如果有人能帮忙那就太好了！

安装wireguardVPN 软件时，它会安装wireguarddkms 内核模块。在 Ubuntu 20.04 之前，这是没问题的。从 20.04 开始，这个内核驱动程序已经包含在内，因此dkms status会显示此错误...

修复方法是在使用 20.04 时删除 wireguard dkms 内核驱动程序...
sudo dkms remove wireguard/1.0.20200413 --all# 从所有内核中删除驱动程序
dkms status现在应该显示...
