Installing wireguard with kernel 5.2.9-kirkwood (5 replies)

Hello.

Has anyone been able to install wireguard from backports with 5.2.9-kirkwood kernel?

I get:

...
Setting up wireguard-dkms (1.0.20210219-1~bpo10+1) ...
Loading new wireguard-1.0.20210219 DKMS files...
Building for 5.2.9-kirkwood-tld-1 5.11.4-kirkwood-tld-1
Module build for kernel 5.2.9-kirkwood-tld-1 was skipped since the
kernel headers for this kernel does not seem to be installed.
...

Previously, I have installed manually the linux-headers-5.2.9-kirkwood-tld-1_1.0_armel.deb package in /boot, but the wireguard module is not build

Am I missing anything?
