Hello everyone,

I got some problems settung up wireguard in a container (Debian 10) using latest Proxmox.

I have seen tutorials, where one needs to install wireguard on the host and add the module via "dkms autoinstall".

However, each time I tried this using pve-manager/6.1-7/13e58d5e (running kernel: 5.3.18-2-pve), dkms was not able to find the linux headers.
Module build for kernel 5.3.18-2-pve was skipped since the kernel headers for this kernel does not seem to be installed.
I know, that one must install pve-headersto get the kernel headers, and I even tried to download and install the pve-headers-5.3.18-2-pve_5.3.18-2_amd64.deb package for my kernel (from http://download.proxmox.com/debian/pve/dists/buster/pve-no-subscription/binary-amd64/). Both tries resulted in no success.
Additionally, setting the kernelsourcedir when trying to execute dkms autoinstall resulted in no luck.

I would like to mention that I managed to set it up on a node that is currently running pve-manager/6.1-5/9bf06119 (running kernel: 5.3.13-2-pve) using the same way.

I read on https://forum.proxmox.com/threads/linux-kernel-5-3-for-proxmox-ve.59398/page-2 that I should install pve-headers-5.3 via apt, no luck (not found).
On https://forum.proxmox.com/threads/linux-kernel-5-4-for-proxmox-ve.66854/ that wireguard-dkms can be installed from buster-backports. This resulted in the same error

How do you do this?

I hope you can help me
Thanks in advance
Schnafi

Hi,

easiest to do it is to add the buster-backports repo:

Bash:
echo 'deb http://ftp.debian.org/debian buster-backports main contrib' >> /etc/apt/sources.list.d/buster-backports.list

update and install the pve-headers (or pve-headers-5.x if one runs older kernel) package, then the wireguard-dkms one:

Bash:
apt update
apt install pve-headers
apt install wireguard-dkms

That works well here.

Thanks for the fast reply.

Well, I tried this right now but I still get:
Error! Your kernel headers for kernel 5.3.18-2-pve cannot be found. Please install the linux-headers-5.3.18-2-pve package, or use the --kernelsourcedir option to tell DKMS where it's located
Additionally, I only see pve-headers-4*** when searching via apt. Do i need to enable pve-testing?
Thanks


I got it, I had stretch in my pve repository
