wireguard package doesn't work on ubuntu eon

[Benjamin]

After upgrading to ubuntu eon, i've tried to install wireguard.
Install went well but wireguard module can't be loaded and so wireguard can't be used.

Ubuntu version: 19.10
Wireguard version: 0.0.20190913-1ubuntu1

When trying to use wireguard:
> sudo systemctl start <email address hidden>
Job for <email address hidden> failed because the control process exited with error code.
See "systemctl status <email address hidden>" and "journalctl -xe" for details.

When trying to load wireguard module:
> sudo modprobe wireguard
modprobe: ERROR: could not insert 'wireguard': Exec format error

I'm happy to provide more info if needed.
Any help would be greatly appreciated!

[Jason A. Donenfeld (zx2c4)]

Run `sudo modprobe wireguard`, and then after run `dmesg`, and paste the output of your dmesg.

Most likely you need to do some sort of dkms rebuilding.

[Benjamin (benjireis)]

Thanks for your quick reply.

Here's the return of `dmesg`:

I've tried to dkms rebuild wireguard module, style same result:
wireguard.ko:
Running module version sanity check.
 - Original module
   - No original module exists within this kernel
 - Installation
   - Installing to /lib/modules/4.15.0-1059-oem/updates/dkms/

depmod...

Weirdly it builds for kernel `4.15.0-1059-oem` instead of `4.15.0-1065-oem`.

[Jason A. Donenfeld (zx2c4)]

[ 15.589541] module: x86/modules: Skipping invalid relocation target, existing value is nonzero for type 1, loc 00000000f4677a21, val ffffffffc1171b82

Looks like a dkms issue? Thankfully we won't need that for 20.04 and also earlier kernels once things are backported. I'll reassign this to the canonical kernel people.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1856539

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Kai-Heng Feng (kaihengfeng)]

What's the output of `dkms status`?

[Avamander (avamander)]

Mine says `wireguard, 0.0.20190913: added`, but updating failed and I suspect it's going to stop working after a reboot.

I'd upload logs with apport but it doesn't let me.

This is what I see in `/var/crash/wireguard-dkms.0.crash`:

This issue is marked as a duplicate of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1858807 so I'm commenting here. Unlink and move comments if they're not actually duplicates.

[MrVantage (mrvantage)]

Looks like I have the same issue. It seems that the wireguard dkms module breaks with a recent kernel patch. I booted into the last working kernel to get the module working again.

The Ubuntu kernel team seems to be behind in deploying a fix for this. In the interim you can solve this by using the WireGuard project's PPA, which now has backports for 19.10. Run this command to fix your issue:

sudo add-apt-repository ppa:wireguard/wireguard && sudo apt-get update && sudo apt-get upgrade
