Too get this latest version of if this will not cause problems ?

I would not do that.  I would use the current version shown for the chimaera release.  Generally speaking, you should not mix "newer" versions of a program unless they were found in the "backports" section of that release cycle.  Even this could be considered for more advanced users.  I would use the version of wireguard for chimaera, as shown  in my first post above.  It works fine and it installs and configures the same way. 

I have some links to the tutorials that I used to configure wireguard, but there are many guides that can be found on the internet.

We can see that the candidate version for wireguard-tools is 1.0.2021 02 23-1

The latest for debian is 1.0.2021 09 14

In Daedalus the candidate version is 1.0.2021 09 14

So I was wondering if we could for example update the /etc/apt/sources to

deb http://deb.devuan.org/merged daedalus          main
deb http://deb.devuan.org/merged daedalus-updates  main
deb http://deb.devuan.org/merged daedalus-security main

Too get this latest version of if this will not cause problems ?

Thanks

I "think" I installed it with

Wireguard works fine.  There are many good tutorials on the web about setting up the keys after installing.

I think the wireguard-dkms and wireguard-modules packages are for the older packages that were before wireguard was included in the kernel.

I would like to install the lastest version of wireguard* on Chimaera.

wireguard as been incorporated into Linux kernel since version 5.6

cat /boot/config-5.10.0-9-amd64 | grep WIREGUARD

ok so my kernel have wireguard as module.

So I presumed I had only need an interface to interact with wireguard.

but
apt show wireguard

apt show wireguard-modules

I'm lost here.

-

apt show wireguard-dkms

I supposes this is required for system that do not have the CONFIG_WIREGUARD ?

apt show wireguard-tools

I see on https://www.wireguard.com/install/#debian-module-tools that the lastest version of tools is v1.0.2021 09 14

Is this version will be compatible with Chimaera ? Is yes, how can I install it ?
