This problems comes from a security update: https://launchpad.net/ubuntu/+source/imagemagick/8:6.8.9.9-7ubuntu5.13

Someone reported it as a bug: https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/1796563

As a temporary fix, I edited /etc/ImageMagick-6/policy.xml and changed the PDF rights from none to read|write there. Not sure about the implications, but at least it allows me to get things done.

You can use ImageMagick (package name: imagemagick) for that job:

convert <SOURCE...> <TARGET>

Example:

convert *.jpg my-collection.pdf

Ubuntu – Converting EPUB to PDF using Pandoc

Have you tried the latest version of Pandoc, which currently is v2.5?
Have you tried to play with '--epub-chapter-level=...' numbers?
Have you tried to play with '--top-level-division=section' (or ...=part or ...=chapter) for the output?
Have you tried with the LuaLaTeX engine`?

pandoc      \
  -f epub   \
  -t latex  \
  -o my.pdf \
  --epub-chapter-level=1 \
  --pdf-engine=lualatex  \
   test.epub

Have you tried a non-Pandoc tool like Calibre?
