i just tested again an install (using the latest musl installer) on an
alpine WSL instance and it works ok; i can also process a tex file (when
i set the path right as reported by the installer)
\starttext test \stoptext :

I tried installing from scratch, and again I now face the exact same failure. I read the install log output a little closer, and noticed this:

mtx-install | running: /opt/context/tex/texmf-linuxmusl-64/bin/context --luatex --generate
mtx-context | redirect luametatex -> luatex: luatex --luaonly --socket "/opt/context/tex/texmf-linuxmusl-64/bin/mtxrun.lua" --generate --redirected
sh: luatex: not found

I wonder if your test environment is really equivalent to a fresh Alpine install, or if there might be any previously installations that are allowing it to appear to succeed. Does it work if you try inside Docker?

I'm not sure what else I can try. Where's that `luatex` call supposed to be found?

Sincerely,
