I need the tiff5 library, but I can not install it without the root permissions on ubuntu 16.04. Does anyone know the method please?
You can try to download the libtiff5 package from https://packages.ubuntu.com/trusty/amd64/libtiff5/download, unpack it, place the libs from usr/lib/x86_64-linux-gnu directory somewhere (i.e. /home/user/custom_libs), and add it to LD_LIBRARY_PATH by the command:
export LD_LIBRARY_PATH=/home/user/custom_libs/
