Comment 1 V Stuart Foote 2020-04-28 22:26:06 UTC 
The PDF opens fine, the issue is that it had been prepared with OCR of the page images.

You can remove the OCR by opening in your PDF viewer of choice and then printing the result back to PDF. Just the page images will be output--none of the OCR text runs.

Alternatively if you prefer, or need the OCR results--you can do that with LibreOffice Draw. It is a manual process where by on each page of the imported PDF you select the source page's image and delete it, leaving the OCR text runs behind.

But, it would be kind of convenient if the pdf import filter offered methods to strip out either the image, or the OCR text when both are present.
