Issue

I added the following to the vignettes in the most recent release to suppress PTEX metadata (for reproducibility reasons):

\pdfsuppressptexinfo=-1

It turns out it's not supported by all LaTeX distros, e.g. if fails with:

LaTeX errors:
! Undefined control sequence.
l.21 \pdfsuppressptexinfo
                         =-1

using

$ texi2dvi --version
texi2dvi (GNU Texinfo 5.1) 5234

which is what we get with CentOS 7.9.

Action

Try with
