Wireguard服务在引导时“不活动(死)”。

Question

我有一个Raspberry Pi 4运行Ubuntu 21.04使用系统安装的Wireguard。它在启动时没有正确启动。我以前安装了Ubuntu20.10，同样的情况也发生在那里。

在靴子上：

$ systemctl status wg-quick@wg0.service
● wg-quick@wg0.service - WireGuard via wg-quick(8) for wg0
     Loaded: loaded (/lib/systemd/system/wg-quick@.service; disabled; vendor preset: enabled)
     Active: inactive (dead)
       Docs: man:wg-quick(8)
             man:wg(8)

             https://git.zx2c4.com/wireguard-tools/about/src/man/wg.8

在运行系统中：

$ systemctl start wg-quick@wg0.service

$ systemctl status wg-quick@wg0.service
● wg-quick@wg0.service - WireGuard via wg-quick(8) for wg0
     Loaded: loaded (/lib/systemd/system/wg-quick@.service; disabled; vendor preset: enabled)

该服务看起来已被禁用：

$ systemctl status wg-quick@wg0.service
● wg-quick@wg0.service - WireGuard via wg-quick(8) for wg0
     Loaded: loaded (/lib/systemd/system/wg-quick@.service; disabled; vendor preset: enabled)
                                                            ^^^^^^^^-- here

..。使其具有以下功能：

sudo systemctl enable wg-quick@wg0.service
