From the vips's website I can only find this information about installing the package
libvips. In Ubuntu 16.04 it will automatically switch to libvips42. It installs mainly the
/usr/lib/x86_64-linux-gnu/libvips-cpp.so.42.3.2 /usr/lib/x86_64-linux-gnu/libvipsCC.so.42.3.2 /usr/lib/x86_64-linux-gnu/libvips.so.42.3.2
However I actually want to install is the utility commands such as
vipsthumbnails. What is the right package for them?
