I am using the documentclass provided by revtex (https://ctan.org/tex-archive/macros/latex/contrib/revtex). It used to work, but I have recently started to get the following error. The document still mostly compiles fine, has a weird \begin{document} at the start. I have tried reinstalling everything, to no avail. I would appreciate any hints, I'm copying the terminal output below. I'm using the newest Ubuntu, revtex, and all packages are upgraded fully.

LaTeX file:

\documentclass{revtex4-2}
\begin{document}
\end{document}

    line 17 of that log looks very suspicious:-) Aug 20, 2021 at 21:36

    theer was a change in \document (which prompted revtex4-2 update) but your test document runs with texlive 2020 and texlive 2021 I just checked Aug 20, 2021 at 21:37
  • the revtex version looks a bit old, and it comes from a different location than e.g. url.sty. Aug 20, 2021 at 21:38

    You say you tried reinstalling, but that does not affect your local texmf tree. I don't know whether revtex is by default in the ubuntu distribution. If yes, you should remove your (non up-to-date) local one, as it takes precedence; if not, you should download the newest version manually in your home.

    apparently that was a known issue and it's fixed in the currect revtex 4-2 (4.2c) which should have the version string [2020/10/03 4.2e (https://journals.aps.org/revtex/ for documentation)]% \fileversion You have 4.2c Aug 20, 2021 at 23:24

As @David Carlisle pointed out in comments this error is caused by having an old version of revtex.

The issue arises because the direct download provided on the APS page (https://journals.aps.org/revtex/revtex-faq#download) gives version 4.2c, and not 4.2e. This can be checked by including \listfiles in the preamble, for example

\documentclass{revtex4-2}
\listfiles
\begin{document}
\end{document}

The error can be fixed by downloading the current version from CTAN instead: https://ctan.org/tex-archive/macros/latex/contrib/revtex
