If you, like myself, are an avid family history researcher or simply good person, you might be participating in FamilySearch’s indexing effort. Basically it’s crowdsourcing the indexing of billions, probably trillions, of family history related images and records so that anyone looking for those records can find them. Pretty important!

But if you go to install the app in Ubuntu 14.04 you may get an error which says:

java.lang.NoClassDefFoundError: java.awt.Container

Most of the help you’ll find for the error is for a prior version. Skip to the true help: http://software-ninja-ninja.blogspot.com/2013/11/stupid-java-error-javalangnoclassdeffou.html

To sum up, you have to add these packages:

sudo apt-get install libgtk2.0-0:i386 libxtst6:i386 libxtst6:i386 libx11-dev:i386  lib32z1 lib32ncurses5 lib32bz2-1.0 libxi6 libxtst6 libxrender1

And run the installer with these flags:

./Indexing_unix.sh -J-Djava.awt.headless=true

That will run it on the command line rather than a window. Note that you may get a window that opens and complains about something. Just cancel that and ignore. Look back at the terminal and proceed.
