I've been using the same resources and script to build an iso for the past few weeks. As of a couple days ago, I am unable to produce an ISO. There seems to be one area failing, apt-xapian-index chroot hook, and the only aid it gives is to check the error log (which is where I am getting the mesage). It seems that the file

lb chroot_hooks
P: Begin executing hooks
Segementation fault
E: chroot/root/lb_chroot_hooks/0310-update-apt-xapian-index.chroot failed (exit non-zero)
is not exiting 0 / sucess

Does anyone have any ideas/directions to solve this?

OR does anyone know if I can complete a successful build without the file?
