I'm installing Arch Linux, following the instructions at the Beginners' Guide, and got up to running
pacstrap -i /mnt base base-devel.
It finishes with the following error:
resolving dependencies... looking for inter-conflicts... error: failed to prepare transaction (could not satisfy dependencies) :: virtualbox-guest-modules: requires linux<3.15 ==> ERROR: Failed to install packages to new root
What is really weird is that I'm not installing Arch in a virtual machine, I'm setting it up to dual boot on my laptop.
