ImportError: libjpeg.so.8: cannot open shared object file: No such file or directory

[A108669]

I am attempting to install geonotebook on ubuntu 16.04 following the installation instructions instructions in the readme

I have successfully installed the prerequirements and requirements

pip install -r prerequirements.txt
pip install -r requirements.txt
pip install .

When I attempt to activate the extensions with the following I run into errors:

jupyter serverextension enable --sys-prefix --py geonotebook
jupyter nbextension enable --sys-prefix --py geonotebook

Errors:

 ubuntu@ip-10-0-10-155:~/jpeg-8d$ jupyter nbextension enable --sys-prefix --py geonotebook

ImportError: libjpeg.so.8: cannot open shared object file: No such file or directory

I am having a heck of a time tracking down what libjpeg.so.8 is and now to install it. Do you have any context that many help me out?

Found a fix:

sudo apt-get install libjpeg-turbo8

A similar issue is posted here. I am glad you figured it out.

That or compiling from source works too: http://www.ijg.org/files/ Make sure to use jpegsrc.v8.tar.gz if you're on a Unix like system though (jpegsr8.zip appears to be the MS version, throws all standard formatting errors while building :/ )
