I have the same issue on multiple servers running ubuntu 16.04 or 18.04 since the 9.26 upgrade. In order to convert a PDF file in PNG I use the command: » convert "myfile.pdf[0]" test.png Which gives this error: convert-im6.q16: FailedToExecuteCommand `'gs' -sstdout=%stderr -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4 '-r72x72' -dFirstPage=1 -dLastPage=1 '-sOutputFile=/tmp/magick-11774WIkYdVETEs9I%d' '-f/tmp/magick-11774JZhknqCDhkN0' '-f/tmp/magick-11774twGtf-JFihri'' (-1) @ error/delegate.c/ExternalDelegateCommand/462. convert-im6.q16: no images defined `test.png' @ error/convert.c/ConvertImageCommand/3258. So I tried using ghostscript directly: » ghostscript -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=pngalpha -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r72x72 -dFirstPage=1 -dLastPage=1 '-sOutputFile=test.png' '-fmyfile.pdf' Which gives an error: GPL Ghostscript 9.26 (2018-11-20) Copyright (C) 2018 Artifex Software, Inc.
