I'm trying to use texdoc, but
$ texdoc babel
texdoc error: No texlive.tlpdb nor shipped tlpdb data found.
A quick search made it sound like that file should be provided upon installation.
I have world/texlive-core 2020.54593-2 installed.
you mean this open bug in archlinux? https://bugs.archlinux.org/task/60013
