Error 500 when trying to start the service

[davidszerman]

Hello,

i installed (reinstalled, restarted the server..) wireguard but it keeps failing

When I try to connect my client, it keeps trying to handshake.

When I run a diagnosis of my Yuno instance, it says that wg-quick0 service is down.

i try to start it :

Thank you for your help

Please use the "Share with YunoPaste" green button from the service log menu. This is unreadable. :/

Can you also share the output of sudo cat /etc/sysctl.conf | grep ipv6 ?

@tituspijean Same error here. Everything worked fine, today I did reboot the server for the first time since April. All apps have been updated before. The wireguard handshake fails since, logs here: https://paste.yunohost.org/enevebezux

Jul 23 20:57:58 wg-quick[1362]: RTNETLINK answers: Operation not supported
Jul 23 20:57:58 wg-quick[1362]: Unable to access interface: Protocol not supported

These mean somehow WireGuard is not loaded in the kernel. :(

Can you share the output of sudo dkms status ?

wireguard, 1.0.20210219, 4.19.0-20-amd64, x86_64: installed

The output of sudo modprobe wireguard : modprobe: FATAL: Module wireguard not found in directory /lib/modules/4.19.0-21-amd64

Weird. Can you try force-upgrading the app? sudo yunohost app upgrade wireguard -F

Weird. Can you try force-upgrading the app? sudo yunohost app upgrade wireguard -F

Thanks, the forced upgrade followed by a reboot solved the problem. Everything is working fine again!
