I ended up with this on ubuntu 18.04 and texlive 20200120:

tlmgr install scheme-basic \
amsfonts amsmath \
babel biber biblatex bibtex bidi bitset booktabs \
collection-context collection-luatex collection-xetex csquotes \
ec \
fancyvrb filehook fontspec footnotehyper \
geometry graphics \
hyperref \
iftex \
letltxmacro listings lm lm-math lualatex-math luaotfload \
mathspec microtype \
natbib \
oberdiek \
parskip pdfescape polyglossia \
setspace \
tools \
ulem unicode-math upquote \
xcolor xurl \
zapfding

I had to add bitset, letltxmacro and pdfescape, and replace ifluatex and ifxetex with iftex. I didn't check whether that was a minimal list.
