I just did a do_release_upgrade with my Ubuntu from Ubuntu 18 to Ubuntu 20, which of course also updated a lot of TeX. Since then, the following minimal example

\documentclass{article}
% \def\pgfversion{42} %% Adding this doen't help
\usepackage{pstricks}
\begin{document}
\end{document}

results in the following

This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/Debian) (preloaded format=pdflatex)
 restricted \write18 enabled.

?

Apparently, \pgfversion is not (yet) defined when needed (inside the \usepackage{pstricks}) .

Q: What's wrong? no package seems to desire update.

As a workaround, I tried adding \def\pgfversion{42}, but that doesn't change anything, i.e., inside the \usepackage, the \pgfversion is still undefined.

Edit: I'm using TeX-live. For convenience, I replaced pst-text with the more immediate pstricks and added the complete output above in order to make the used filenames clear.

  • ??? What does pgf have to do with pstricks? – Bernard Jan 13 '21 at 14:16
  • @Bernard It seems that pstricks.sty includes pstricks.tex, which again includes (among others) pgffor.code.tex, where the error happens – Hagen von Eitzen Jan 13 '21 at 14:52
  • Yes, pstricks loads pgffor; yet I have no problem with it (I'm under MiKTeX – would it be a problem with Ubuntu, or with TeX Live?? – Bernard Jan 13 '21 at 14:57
  • For me the code compiles without problems with the Debian distribution of TeX Live 2019 under Ubuntu 20.04 (so the same as you have presumably), both with latex and pdflatex. – Marijn Jan 13 '21 at 18:47

I had the same problem when performing the same upgrade.

I was able to fix it by editing the file /path/to/texmf/tex/generic/pgf/utilities/pgffor.code.tex and commenting out the line \ProvidesPackageRCS[v\pgfversion] $Header: /cvsroot/pgf/pgf/generic/pgf/utilities/pgffor.code.tex,v 1.25 2013/12/13 11:40:27 tantau Exp $
