Can you provide the contents of your script for debugging purposes?

@oxr463, It is an application called AndroNix that provides linux installation codes using termux terminal, and my phone system is miui 11 (android 10), does termux support android 10?

the content of the script 'start-ubuntu19.sh':

cat start-ubuntu19.sh

#!/data/data/com.termux/files/usr/bin/bash
cd $(dirname $0)
# # unset LD_PRELOAD in case termux-exec is installed
unset LD_PRELOAD

if [ -n "$(ls -A ubuntu19-binds)" ]; then
    for f in ubuntu19-binds/* ;do
      . $f
    done
fi
