Live build hook 0140 permission dennied error

I'm trying to build a custom ISO without the beep at boot. Just edited the menu.cfg file and followed the instructions from the oficial guide (https://www.kali.org/docs/developmen...stom-kali-iso/) but I keep getting the following error:
build.log

I've tried running the 0140-remove-log-files.hook.chroot as a regular user and as a root but still getting the same error. Tried chown the postgresql-12-main.log file to the give the regular user ownership but stil no luck. Also tried running the script in bin/bash and the error is the same.

uname -a

Any help on how to proceed or fix this would be appreciated!

The problem comes from the sticky bit set on the /var/log/postgresql dir.

This doesn't work even if we are running as root :

Code:

---

: > postgresql-12-main.log

---

This would work:

Code:

---

truncate -cs 0 postgresql-12-main.log

I am currently facing the same error. Can anyone shed light on this problem?
