I tried to convert my thesis from Latex to required pdf/a - version 2u. However, two problem occured from a validation test.
Firt one: "The key F is required but missing."
I failed with googling it, i think that it has maybe something to do with links. I came across one forum, but I do not understand (probably they are not working in LaTeX) - https://forums.adobe.com/thread/1023316
Then, I tried to find the sollution on our forum, but no one had really the same problem. E.g. I tried to use sollution from this post PDF/A with hyperref on TeX Live 2013, but the validator told me, that I have pdf1.4, not even pdf/A.
Does anybody know, what should I change to get rid of this "F key" or how to deal with it?
Second problem, which is probably not so important: The document contains hidden, invisible, non-viewable or non-printable annotations.
I don't know, what they mean by that exactly. Is there a problem with my notes (meaning text starting with %). Does anybody know the sollution?
My code in preambule, packages used are at the end:
\documentclass[openany,hidelinks]{book} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage[czech]{babel} \usepackage{fancyhdr} \usepackage{float} \usepackage{graphicx} \usepackage{amsmath,amssymb,amsthm} \usepackage{color} \usepackage[round]{natbib} \usepackage{hyperref} \usepackage{bookmark} \usepackage[normalem]{ulem} \newcommand{\myand}{\&\ } \usepackage[acronym]{glossaries} \makeglossaries \useunder{\uline}{\ul}{} \numberwithin{equation}{chapter} \usepackage{longtable} \usepackage{array} \usepackage{regexpatch} \makeatletter \xpatchparametertext\@cline{-}{\cA-}{}{} \usepackage{placeins} \usepackage{booktabs} \usepackage{caption} \usepackage{pdfpages} %for pdfA \usepackage{xmpincl} \usepackage[a-2u]{pdfx} \usepackage{lmodern} \usepackage{textcomp} I would be very grateful for every answer! :) Thank you.
The problem is with my bibliography! Another validator gave me exact pages of the problems. And it looks like this: root/document[0]/pages[54](825 0 obj PDPage)/annots[16](821 0 obj PDAnnot)
Second error has this description:root/document[0]/pages[64](935 0 obj PDPage)/contentStream[0](936 0 objPDContentStream)/operators[556]/font[0](BCVKHY+LMMathSymbols10-Regular)
root/document[0]/pages[64](935 0 obj PDPage)/contentStream[0](936 0 objPDContentStream)/operators[611]/font[0](HVVRCK+LMMathSymbols7-Regular)
