Expected Build Warnings
  1. Nothing to worry about. Only happens because we are running commands inside chroot. If you research this "issue", you'll read that it is purely cosmetic.
  2. KVM gets installed as dependency of our build dependency libguestfs-tools. We don't need KVM for building the actual images.
  3. Only means, that VirtualBox can not be started. VirtualBox kernel modules could not be complied, because the linux-headers-$(uname -r) package was not installed prior installing VirtualBox (prior starting Whonix's build script). The build script doesn't start VirtualBox, hence does not affect the build. The build script only uses VBoxManage for creation of virtual machine description files and that tool doesn't need VirtualBox kernel modules.
  4. Same as above.
  5. This happens because we are running debuild as user, not root. Probably a bug in dpkg. If you research this, you'll see, there were many such bugs in dpkg.
