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" />

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.
