带有 18.04 和内核 5.3.0-53-generic 的 WireGuard ppa？

Question

我今天运行了更新和升级，但无法启动 WireGuard：

$ sudo wg-quick up wg0
[#] ip link add wg0 type wireguard
Error: Unknown device type.
Unable to access interface: Protocol not supported

清除并重新安装 WireGuard 会导致：

最初，我用 ppa:wireguard/wireguard 安装了它 - 现在这个内核的安装是否不同？

Answer 1

此后，wireguard-dkms 已更新。1.0.20200506-1~18.04版本修复了这个问题。现在，它适用于内核 5.3.0-53，但它不再适用于 5.3-051 版本...

Answer 2

在 5.3.0-1020-azure 中遇到了同样的问题。对于那些无法升级/降级其内核的人（例如 GitHub Actions 中的托管 CI 运行程序），安装一些旧版本是有效的：

sudo apt install dkms

curl -L -o wireguard-tools.deb https://launchpad.net/~wireguard/+archive/ubuntu/wireguard/+build/19291633/+files/wireguard-tools_1.0.20200510-1~18.04_amd64.deb
curl -L -o wireguard-dkms.deb https://launchpad.net/~wireguard/+archive/ubuntu/wireguard/+build/19258545/+files/wireguard-dkms_1.0.20200429-2~18.04_all.deb

sudo dpkg -i wireguard-tools.deb
sudo dpkg -i wireguard-dkms.deb

sudo modprobe wireguard
