In essence, this is my question found at https://tex.stackexchange.com/questions/602194/installing-texlive-2021-i-cant-find-file-dehypht-x-2021-02-26-tex but with a few minor updates.

But, as of recently, I cannot build docker images for some TeXLive schema (as of this writing it fails for tl-20210701, but also didn't work with tl-20210622); my weekly builds fail already at installing the minimal scheme.

I slightly modified your texlive.profile (in order to change the
directories as I wanted to install the files elsewhere, not under
/usr/local/texlive, and I didn't use Docker, I just installed directly
to an existing linux distro) and I wasn't able to reproduce the
problem.

It seems that in your case tlmgr finds
    /usr/local/texlive/texmf-dist/tex/generic/config/language.def
instead of either of those two:
    /usr/local/texlive/texmf-var/tex/generic/config/language.def
    ~/.texlive/texmf-var/tex/generic/config/language.def

The file
    /usr/local/texlive/texmf-dist/tex/generic/config/language.def
contains a pre-generated list with all hyphenation patterns, while
tlmgr is supposed to use a list that's generated on the fly based on
what packages you have installed.

As to why this happens ... I leave that question to the others.
(I'll revert my change from yesterday, it was wrong.)

Btw, why is the following path using a double slash?
    TEXMFSYSVAR /usr/local/texlive//texmf-var
