Can you please send me the output of 'uname -a'. Thx.

Linux route-extern.xxx.xx.xx 4.19.4-amd64-vyos #37 SMP Mon Nov 26 10:03:40 CET 2018 x86_64 GNU/Linux

Kernel module hasn't been rebuilt on our side. The current package will put that under /lib/modules/4.19.0-amd64-vyos/extra/ and your kernel is 4.19.4 and won't find it. I have a look into the package right now.

Please download http://dev.packages.vyos.net/repositories/current/vyos/pool/main/w/wireguard/wireguard-modules_0.0.20181018-1_amd64.deb and install via 'dpkg -i <pkg name>'.

Umm, that's not what happened. It looks like it needs to be in the 4.19.0 directory to work

admin@route-extern:~$ ls -al /lib/modules/4.19.0-amd64-vyos/extra/
total 70
drwxr-xr-x 2 root root    49 Nov 26 19:29 .

admin@route-extern:~$ ls -al /lib/modules/4.19.4-amd64-vyos/extra/

Hmm. looks strange. 4.19.0-amd64-vyos isn't required as you are running on 4.19.4-amd64-vyos. Can you load the module manually? (sudo modprobe wireguard).

That didn't do anything.

admin@route-extern:~$ sudo dpkg -i wireguard-modules_0.0.20181018-1_amd64.deb
(Reading database ... 53060 files and directories currently installed.)

Reboot

This file still exists as before:

admin@route-extern:~$ ls -al /lib/modules/4.19.4-amd64-vyos/extra/wireguard.ko
-rw-r--r-- 1 root root 323200 Nov 25 13:23 /lib/modules/4.19.4-amd64-vyos/extra/wireguard.ko

But the module is failing like it's corrupted (same output of trying to add a wg0 interface manually):

admin@route-extern:~$ sudo modprobe -f wireguard
modprobe: ERROR: could not insert 'wireguard': Exec format error

Hmm, ok I gotta check on that.

As another question, is that a bug that ipoe.ko and vlan_mon.ko are ending up under the old kernel modules?

Well not really, the ones who rebuilt the new kernel didn't know about those. I'm working on IPoE integration (similar like a PPPoE server but without the PPP =), They won't do anything.
