I have TeX Live 2019 on my computer and I need to update a single package, but TeX Live 2020 was already released a month ago, so I am getting such a message
tlmgr.pl: Local TeX Live (2019) is older than remote repository (2020).
Cross release updates are only supported with
update-tlmgr-latest(.sh/.exe) --update
See https://tug.org/texlive/upgrade.html for details.
whenever I try to run tlmgr update --all
I was looking for the solution, but most seem to be outdated. Can you help me with such a problem?
