Unable to locate package leptonica

When I run

./install_requires_related2opencv.sh

I get the error mentioned in the title. I have run sudo apt-get update.

liblept5 does seem to exist. Perhaps that will work?

I just noticed this when doing an upgrade:

The following packages were automatically installed and are no longer required:
  libtesseract-data libtesseract3 tesseract-ocr-eng tesseract-ocr-equ
  tesseract-ocr-osd
Use 'sudo apt autoremove' to remove them.

I solved it by replacing package name leptonica with libleptonica-dev
