Make kernel-config does not work on current github fenix

Still error. See below history what I did:

177 mkdir project
178 cd project/
179 git clone --depth 1 GitHub - khadas/fenix: One-stop script set to build Ubuntu/Debian images
180 cd ~/project/fenix
181 source env/setenv.sh
182 make help
183 make kernel-config

It then ran though a number of steps and failed here

make: *** [Makefile:39: kernel-config] Error 1

THIS IS THE SETUP:
4. VIM3
2. uboot-mainline

  1. linux-mainline
  2. Ubuntu
  3. focal
  4. minimal
  5. SD
    N. Do not compress

if I however add this line in ./fenix/config/functions/build
LINUX_DIR=/home/ubuntu/dashcam/fenix/build/linux-mainline-5.12

then it works. So it appears that LINUX_DIR is not setup correctly.
