How can I set chown and chmod permanently, also for new files?

I installed texlive as usual in /usr/local/texlive/2025. When installing I typed umask 0027 prior to each command (./configure, make...), hoping that the resulting files would have root as owner and me as group with the same rights to access, read and change the files. Nevertheless, when updating texlive (sudo tlmgr --self --all --no-auto-remove update), the owner becomes root, the group becomes root instead of ME, and I neither can use commands like luatex nor the .sty files etc., as they're owned by root. So, each time I update texlive via tlmgr I have to change owner and group manually for all files in \textlive\2025. What can I do to set owner=root and user=ME for all files newly created and changed with sudo tlmgr ... in the future?
