We can't get to the pdf in question directly and the page that offers it does not offer a direct link. That makes this question inconvenient for discussion.
The document in question is an Adobe LiveCycle Designer file, which in my opinion should not be labeled as a "PDF" file because it does not comply with the open standards for a PDF file. It is an XFA form document.
See here about the fact that XFA is not part of the open PDF standard, it is a proprietary Adobe hack that is now deprecated by ISO TC 171: https://en.wikipedia.org/wiki/Portable_Document_Format
My instinct is to tell Adobe to jump in the ocean and forget about their stupid format, but if you are determined, it appears the best options are to run Adobe Reader DC inside Wine (or similar)
Or Use Adobe DC to convert that LiveCycle Designer file to a PDF:
However, this seems like a bad idea to me because we are forced back into a closed technology that Adobe owns and only Adobe can open. It is not a legitimate PDF, if PDF is still supposed to mean "portable document format". Which this LiveDesigner file is not.
