First I just downloaded the pre-built binary as described here

/usr/local/bin$ sudo wget https://imagemagick.org/archive/binaries/magick

but trying to run it gives this:

$ sudo chmod +x magick
$ magick -version
dlopen(): error loading libfuse.so.2

AppImages require FUSE to run.
You might still be able to extract the contents of this AppImage
if you run it with the --appimage-extract option.
See https://github.com/AppImage/AppImageKit/wiki/FUSE
for more information

So the next step is to install FUSE [1]

$ sudo add-apt-repository universe
$ sudo apt install libfuse2

but still no luck:

$ magick -version
/tmp/.mount_magickwccjeB/usr/bin/magick: error while loading shared libraries: libharfbuzz.so.0: cannot open shared object file: No such file or directory

next run this [2]:

$ sudo apt install libharfbuzz0b

after this it works:

$ magick -version
