I have inserted inputs to a form given as a PDF file. Using Evince document viewer 3.2.1 on Ubuntu 11.10, there is no problem with inserting inputs to the form and to print the result.
But it is not possible to save the PDF file with inputs (as a new file) and the following error message is given:
The file could not be saved as "file:///home/username/Downloads/file.pdf" Document is encrypted
Note for the message above that if I try to save the file in a different folder (e.g. Documents), the error message is still referring to the Downloads folder.
How to save the PDF file with inputs?
P.S. I know that similar questions are in the database, but I have not seen a similar error message in previous questions
