strange script

[Fskadi]

i followed the tutorial as written, only i changed the username in my username and it didn't want to take the passwd, apart from it i think i followed all

this is what i get after i restarted the phone and got into su

.../local/tmp $ su
:/data/local/tmp # ls
ArchLinuxARM-aarch64-latest.tar.gz
chrootarch
start_arch.sh
startxfce4_chrootArch.sh

when i try to install the packages it says they are already installed

what i'm doing wrong? also before this i couldn't open the script with ./ only with sh works, when i use ./ it says no file or directory even when i'm in folder and the file is here and it has necessary permissions
thank you

for anyone having the same problem i had to install termux x11 arm64 debug from github,
mkdir -p /data/local/tmp/chrootarch/dev/shm
and it worked, thanks for the tutorial
