“[email protected] 作业失败，因为控制进程退出并出现错误代码”

我正在尝试按照视频教程之一在 Ubuntu 18.04 64 位上安装wireguard。

步骤结束于systemctl start [email protected]

Job for [email protected] failed because the control process exited with error code. 
See "systemctl status [email protected]" and "journalctl -xe" for details.

运行给出：systemctl status [email protected]

跑步journalctl -xe节目：

Mar 10 23:46:27 my-vps.name wg-quick[18951]: Cannot find device "wg0"

我的wg0.conf样子：

[Interface]
PrivateKey = myprivatekeyhere
Address = 10.0.0.1/24
ListenPort = 51830
PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -t nat -A POSTROUTING -o venet0 -j MASQUERADE
PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -t nat -D POSTROUTING -o venet0 -j MASQUERADE

modprobe wireguard说：

modprobe: FATAL: Module wireguard not found in directory /lib/modules/4.15.0

ls /lib/modules返回：

4.15.0  4.15.0-206-generic

uname -r显示：

4.15.0

重新启动没有帮助。搜索没有帮助。

答案1

所以，是的，正如错误所说：您的内核没有wireguard模块，因此无法执行wireguard。

您需要构建并安装wireguard模块（因为您使用的是非常旧的发行版，内核很旧，所以内核中没有wireguard，您需要单独安装它；如果您启用了universe repos，请安装wireguard-dkms。更好，更新到更现代的 Ubuntu；从那时起，任何具有 Linux 内核 > 5.6 的系统都可能包含wireguard 模块；因此，请选择 Ubuntu 22.04）
