Now that you mention it, would it be possible to have virtualbox depend on a "virtualbox-host" fake package that both virtualbox-host-modules and virtualbox-host-dkms Provide? That way end users wouldn't need to install any headers or make dependencies, and their updates would be faster, while folks on other kernels would still be able to satisfy the dependency their own way. Or is there another reason virtualbox-host-modules was dropped as a dependency? Unfortunately, "virtualbox-host" wouldn't automatically fix anyone who's gotten into the broken state, since they'll now have virtualbox-host-dkms installed, but it won't be building any vbox* modules for them. Maybe it would be a good idea to create *both* virtual packages? If that's more work than it's worth, an Arch News post might do the trick too. But people using virtualbox-host-dkms really do require at least one kernel package, and it could be helpful to have pacman enforce that.

(Or would that mean that the > different header packages conflict where they didn't before?) Yes, I think that would be the best solution. Each '*-headers' package could provide 'kernel-headers' (or something like that). Provides does not imply conflict, so that wouldn't be a problem. Note that a user could still install a certain 'x-headers' which does not match their 'y' kernel, since the headers do not depend on the kernel or vice versa. (in the libgl case this is not a problem, since the libgl packages depend on the matching driver) But I think most users who use the regular kernel and are not familiar with other kernels would install the plain 'linux-headers' package when prompted, and not the 'linux-lts-headers' package or something else.

Would it be possible to depend on a "Provides" that all the different kernel header packages share? Similar to how nvidia-libgl, catalyst-libgl, and mesa-libgl all provide the "libgl" dependency. That would solve the presumably-very-common case where users initially installed virtualbox without any host headers at all, and are now landing in a broken state by default. (Or would that mean that the different header packages conflict where they didn't before?) - Jack

Just to make it clear, to avoid any misunderstanding. You need the kernel source code to compile the modules. This is not only a requirement when building kernel modules. The linux packages are just split into the kernel image and header packages, while other packages usually aren't split and contain their header files.

You're right, that could be unfair esp when you install kernels via aur. Is it possible to add a hint while installing the package? I know theres already an opt dep but for me an opt dep is very optional but in this case you really need some headers to get the modules working. Cheers Chris

Hi, you miss that the official provided linux and linux-lts headers are already optional dependencies [rocketmouse@archlinux ~]$ pacman -Qi virtualbox-host-dkms | grep -A1 Optional\ D Optional Deps : linux-headers [installed] linux-lts-headers and an example from one of my bash histories [root@archlinux rocketmouse]# grep dkms ~/.bash_history | grep 5 dkms remove -m vboxhost -v 5.0.12 --all dkms install vboxhost/5.0.14 -k 4.3.3-3-ARCH/x86_64 && dkms install vboxhost/5.0.14 -k 4.0.4-rt1-1-rt/x86_64 && dkms install vboxhost/5.0.14 -k 3.10.61-rt65-1-rt-lts/x66_64 as you can see, a kernel not necessarily is provided by official repositories so you can not make such headers hard dependencies and I not necessarily have linux or linux-lts from official repositories installed at all, so I also don't want to be forced to install the headers.

I guess what you are missing is that it is already an optdepends. It would be rather unfair towards users of a different kernel to make a hard dependency on the main kernel. -- Eli Schwartz
