Re: /usr/bin/env texlua no such file or directory; ~/context/tex is not a valid TEXROOT path; no file plain.tex

Hi Carlos,

I think that you may be installing the old ConTeXt MkIV distribution
instead of the new ConTeXt LMTX. ConTeXt LMTX doesn't distribute
"texlua" at all, and running 
"./install --modules=all" doesn't make sense with LMTX (since the
installer can't install modules).

From what link did you download your ConTeXt? If it started with
"minimals.contextgarden.net", then that's the old ConTeXt; if it started
with "lmtx.pragma-ade.com" then it's the new LMTX. The wiki page that
you want is

   https://wiki.contextgarden.net/Installation#Unix
   
All the other wiki pages are outdated. 

This is just a wild guess, so I may be very wrong here.

If this doesn't work, then what do you get when you run

   type -ap context
   type -ap luatex
   type -ap texlua
   type -ap luametatex
   /full/path/to/texlive/2023/context --version
   /full/path/to/context/standalone/context --version
   ls -la /full/path/to/texlive/2023/context
   ls -la /full/path/to/context/standalone/context

(I'll also add that I have both the ConTeXt and TeX Live versions of
"context" installed on Linux, so it's definitely possible.)

Thanks,
-- Max
