workaround: build with linux-lts kernel version

If after updating amneziawg-linux awg-quick doesn't use this kernel module, you need to rebuild amneziawg-tools and amneziawg-go (idk which of them explicitly causes this problem)

I've removed hard depend on version of linux package. You may try to build it now.

error: failed to prepare transaction (could not satisfy dependencies)
:: installing linux (6.12.3.arch1-1) breaks dependency 'linux=6.11.6.arch1-1' required by amneziawg-linux
:: installing linux-headers (6.12.3.arch1-1) breaks dependency 'linux-headers=6.11.6.arch1-1' required by amneziawg-linux
 -> error installing repo packages

I double-checked everything and was able to reproduce the error. For some unknown reason, all package managers working with AUR determine the dependencies of the pkg{} block before building, and not during packaging, as intended in this PKGBUILD. This causes some inconvenience - a hard link to the linux version is needed for correct updating of the kernel in the future - you will also need to update the amneziawg-linux package, otherwise the kernel will be updated and the module will stop working. I don't know how to solve this problem yet, I will try different options.

No packages amneziawg-linux, linux-headers, linux in cache.

Can you clear your yay cache (build directory)?
