Are you certain that the dkms rebuild was triggered?  Seems like like it was not.  Perhaps manually trigger it and reboot.<br><br>On Monday, November 19, 2018, Tosh &lt;<a href="mailto:tosh@t0x0sh.org">tosh@t0x0sh.org</a>&gt; wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello,<br>

I&#39;m using Wireguard on ArchLinux since a long time, and today I have<br>
some troubles to start my VPN. Here is the log of dmeg when I try to<br>

I did a MAJ of my system yesterday, but wireguard wasn&#39;t upgraded, so I<br>
don&#39;t know where the problem come from...Seems a LKM related to crypto<br>
is missing, but I don&#39;t know which one is.<br>
<br>
My kernel is 4.19.2-arch1-1-ARCH, and my wireguard packages are :<br>
<br>
- community/wireguard-dkms 0.0.20181115-1<br>
<br>
- community/wireguard-tools 0.0.20181115-1<br>

Thanks for your work,<br>
