Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
To fix this problem one has to fix the paths in
/usr/lib/GraphicsMagick-1.3.42/config/type-ghostscript.mgk file
To workaround this issue, install the fonts that comes with ghostscript-fonts-
std-8.11.tar.gz in the paths that you see in above `.mgk` file.
I have installed
ii graphicsmagick-imagemagick-compat 1.4+really1.3.42-1
all image processing tools providing ImageMagick interface
Run the following command
convert -size 1366x720 -background cornsilk -fill blue -pointsize 12 -font
FreeMono -gravity center label:'Some Random Screenshot' screenshot.png
You will see the following error
convert: Unable to get type metrics (Some Random Screenshot).
Run the following command
~$ gm convert -list font
Path: /usr/lib/GraphicsMagick-1.3.42/config/type-ghostscript.mgk

Mapping for URW Standard postscript fonts (cyrillicized)
Download from https://src.fedoraproject.org/repo/pkgs/urw-fonts/
(https://src.fedoraproject.org/repo/pkgs/urw-fonts/urw-
fonts-2.0.tar.bz2/c5cc8237e4289fc6ebeaa296174fa504/urw-fonts-2.0.tar.bz2)
NetBSD's pkgsrc (http://pkgsrc.se/fonts/urw-fonts) calls these "urw-
fonts-2.0nb1".
metrics="/usr/share/fonts/type1/gsfonts/a010013l.afm"
glyphs="/usr/share/fonts/type1/gsfonts/a010013l.pfb"
metrics="/usr/share/fonts/type1/gsfonts/a010033l.afm"
glyphs="/usr/share/fonts/type1/gsfonts/a010033l.pfb"
metrics="/usr/share/fonts/type1/gsfonts/a010015l.afm"
glyphs="/usr/share/fonts/type1/gsfonts/a010015l.pfb"
Note that the fonts is coming from /usr/share/fonts/type1/gsfonts/
List the contents gsfonts package
~$ dpkg -L gsfonts
/.

/usr/share/doc/gsfonts/NEWS.Debian.gz
/usr/share/doc/gsfonts/changelog.Debian.gz
/usr/share/doc/gsfonts/copyright
transitional dummy package (gsfonts -> fonts-urw-base35)
Now check the contents of the package fonts-urw-base35
~$ dpkg -L fonts-urw-base35 | grep 'afm\|pfb' | head
/usr/share/fonts/X11/Type1/C059-BdIta.pfb
/usr/share/fonts/X11/Type1/C059-Bold.pfb
/usr/share/fonts/X11/Type1/C059-Italic.pfb
/usr/share/fonts/X11/Type1/C059-Roman.pfb
/usr/share/fonts/X11/Type1/D050000L.pfb
There are afm and pfb files here.
In order to fix this, the paths to font metrics etc has to be fixed in file
/usr/lib/GraphicsMagick-1.3.42/config/type-ghostscript.mgk
~$ dpkg -S /usr/lib/GraphicsMagick-1.3.42/config/type-ghostscript.mgk
libgraphicsmagick-q16-3: /usr/lib/GraphicsMagick-1.3.42/config/type-
ghostscript.mgk
To workaround this bug, I installed the fonts manually in
/usr/share/fonts/type1/gsfonts/
~$ ls /usr/share/fonts/type1/gsfonts/

I used the following instructions
[[https://www.linuxfromscratch.org/blfs/view/svn/pst/gs.html][ghostscript-10.02.0]]
If you have downloaded the fonts, unpack them to =/usr/share/ghostscript= and
ensure the ownership of the files are =root=: =root=.
#+begin_example
tar -xvf ../ghostscript-fonts-std-8.11.tar.gz -C /usr/share/ghostscript --no-
same-owner &&
tar -xvf ../gnu-gs-fonts-other-6.0.tar.gz -C /usr/share/ghostscript --no-
same-owner &&
fc-cache -v /usr/share/ghostscript/fonts/
#+end_example
taking care to replace ghostscript path with gsfonts path.
The `convert` command works now, after my workaround
