setupTermuxArch script do not download .tar file for installation on Chromebook

[JanuszChmiel]

Because I have decided to buy Chromebook computer, I have started to find its big potential on its Android subsystem capabilities.
Unfortunately, My Chromebook which is equipped with Intel CPU X64 Bit computer do not support your excellent script.
I AM running Termux 119.1 available here.
https://apkcombo.com/termux/com.termux/
Sure, I have performed its packages update and upgrade.
But when I execute setupTermuxArch Bash script, it generate The following series of errors.
~ $ bash ./setupTermuxArch

And nothing new happens.
Please, is it technically possible to use ArchLinux on Chromebook on X64 Bit CPU architecture?
Because Chromebook execute Android as a standalonevirtual machine which uses Kqemu and special Rust language app to manage virtual machines.
May be, that this port of Android is much more different than Android build in to ortable devices with ARM CPU.

I have even found out, that it is no more possible to use Xvnc on Chromebook on their Android OS, because special C language function is not implemented.
The question is, if it is possible to add this C language function to Termux .so library or in to Proot for X86 machines.
