## tlmgr: local version is older than remote repository

# sudo tlmgr update --self --all

tlmgr: Local TeX Live (2021) is older than remote repository (2022).
Cross release updates are only supported with
update-tlmgr-latest(.sh/.exe) --update


If you receive an error like this when using tlmgr, it means that it is trying to use a more recent version. It can easily be fixed by running the following command (for example in postCreateCommand or in a pipeline):

# sudo tlmgr option repository ftp://tug.org/historic/systems/texlive/2021/tlnet-final


Warning

The year in the url must match the version shown in the error message.
