I was trying to setup proxy chain for kali linux in termux

root@localhost:~ ./kuburan-repo.sh
bash: ./kuburan-repo.sh: /data/data/com.termux/files/usr/bin/sh: bad interpreter: No such file or directory

To solve this, I followed termux-chroot from here
But now i am getting this errors

$ls
binds start-ubuntu.sh ubuntu.sh kali-armhf storage kalinethunter ubuntu-fs
$./start-ubuntu.sh
proot info: vpid 1: terminated with signal 4 proot error: trying to remove a directory outside of '/data/data/com.termux/files/usr/tmp', please report this error.
$startkali
proot warning: can't sanitize binding "/sys/": No such file or directory proot info: vpid 1: terminated with signal 4 proot error: trying to remove a directory outside of '/data/data/com.termux/files/usr/tmp', please report this error.

I am not able to enter in my linux distro. How to fix this?

Start by reading the mentioned start-ubuntu.sh and ubuntu.sh scripts, then reproduce the failure with proot and inspect the /sys binding warning, signal 4, and cleanup error. Done means the affected Linux distribution starts successfully without these proot errors.
