qubes-builder error: target not found: linux

[Guerlan]

I've ran qubes-builder by selecting ubuntu, debian, arch and kali. However I always end up in this error after running make qubes-vm:

(11/11) Rebuilding certificate stores...

  --> Removing non-required linux kernel (can be added manually through a package)...
error: target not found: linux
make[1]: *** [/home/user/qubes-builder/qubes-src/builder-archlinux/Makefile.archlinux:104: /home/user/qubes-builder/chroot-vm-archlinux/home/user/.prepared_base] Error 1
make: *** [Makefile:226: vmm-xen-vm] Error 1

there's no issues in the github project so I can't talk directly to them

anyone knows what  is happening?
