Hello.
I have a problem with a bulding ipk-files for OpenWRT 24.10.0, which runned under a LXC-container on the VPS-server (Ubuntu 24.04).

First, I've downloaded 3 ipk-files for x86_64 from https://github.com/Slava-Shchipunov/awg-openwrt/releases/tag/v24.10.0.
It installed successfully, without any errors. But when I configured Amnezia-interfaces via luci, the interfaces didn't start.
The log in OpenWRT says something about missing kernel modules:

Mon Apr 14 12:03:14 2025 daemon.notice netifd: Interface 'Keenetic_Net' is setting up now

Kernel info:

~ # opkg info kernel
Package: kernel

Status: install ok installed
Architecture: x86_64
Installed-Time: 1738624177

But it is OpenWRT in LXC, it uses host kernel:

~ # uname -a

Later,
According to the instructions from https://github.com/itdoginfo/domain-routing-openwrt/wiki/Amnezia-WG-Build I tried to build my own Amnezia-modules for my platform. I used the "vermagic: a21259e4f338051d27a6443a3a7f7f1f-r1" from my OpenWRT, but the build stops with an error:

Error: Process completed with exit code 1.

I tried to use the "vermagic: a21259e4f338051d27a6443a3a7f7f1f", without "-r1", the build completed, but finally it didn't work, I received the same error in OpenWRT about missing kernel modules.
I tried to use the "vermagic: 6.8.0-53-generic SMP preempt mod_unload modversions" from the host, but the build doesn't complete with an error about SMP.
I'm a novice, and I don't understand all the process clearly, but I try the best.
Please help me to solve this problem.

I use OpenWRT-image version 24.10 for LXC from https://images.linuxcontainers.org/.
In the host system the kernel is:

~# uname -a
Linux 6.8.0-53-generic #55-Ubuntu SMP PREEMPT_DYNAMIC Fri Jan 17 15:37:52 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

I tried to install vanilla wireguard to OpenWRT via OPKG. It was built for kernel 6.6.73 and it works without any problem.

I did it. I just built and installed AmneziaWg to the host. And after AmneziaWg begun to work in the LXC-container.
