imagemagick - convert not allowed

ImageMagick has some security policies disabling some rights for security reasons. See why at the bottom of this answer.
You will have to edit a config file to re-enble the action you need.

Open /etc/ImageMagick-6/policy.xml with your favorite text editor, find the line <policy domain="coder" rights="none" pattern="PDF" /> and replace "none" by "read|write"

# Open the file 
sudo nano /etc/ImageMagick-6/policy.xml

# find and edit the line
<policy domain="coder" rights="none" pattern="PDF" />
# to :
<policy domain="coder" rights="read|write" pattern="PDF" />

About ImageMagick sercurity policy
The restricted policy is made to prevent unknown vulnerabilities coming from third party software as Ghostscript used here for PDF files. Be sure to update Ghostscript.

Because of a known bug with security implications, the conversion to pdf is disabled in ImageMagick convert.

I suggest that you work around the problem,

  • Import the pictures into LibreOfffice and save the document.

  • Export as pdf from LibreOffice.
