I want to concatenate some PDFs into one via pdftex, so wrote the tex file like:
% foo.tex
\documentclass[a4paper]{article}
\usepackage{pdfpages}
\begin{document}
\includepdf[nup=1x1, pages=-]{01-0_pp_i_iv_Frontmatter.pdf}
% and more
\end{document}
But I got an error while running pdflatex foo.tex:
This is pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017) (preloaded format=pdflatex)
restricted \write18 enabled.

The error says that the PDF is damaged, but, as far as I saw in PDF viewer, PDFs seem to be right.
What does this error (in particular, "Couldn't read xref table") mean? Can PDFs be broken? Or, How can I fix such an error?

I had encountered the same issue, when I inserted several images (in eps format) into the latex document. While it was compiling I had accidentally cleared all the auxiliary files (Using Tools->Clean auxiliary files option in Tex-studio). I was unable to get the output. Then I found that an eps was converted halfway as Pdf (in corrupted condition). I simply deleted that Pdf and guess what, the compilation was successful and I can now view my output.
