ePubChecker

ePubChecker™ is a free app to check your EPUB files for correct format.

To publish your Apple iBook, they require your manuscript be verified by the 'epubcheck' checking engine. Our tool 'ePubChecker' harnesses version 1.0.5 of that engine, making it easy to use on your Mac, PC, or Linux computer.

ePubChecker also harnesses version 0.1.0 of the "epubpreflight" engine to see if your book follows suggestions to give the best results for your readers.

You can find other tools on the Web for checking your file. ePubChecker has a few advantages:

Installing Java is quick, easy, and free of cost. Similar to installing Adobe Flash or Apple iTunes/QuickTime.

Your Linux computer may have Java installed, or it may have an installer ready for you to run.

To see if you have Java installed, run the Terminal program, and type:
java -version
If installed, you'll see a message about 'Runtime Environment' and a build number.

If not installed, you may see a message about:
The program can be found in the following packages:
If found in the list of packages, copy the line containing 'openjdk', and in the terminal do as the message suggests, typing (or copy-pasting) something like this:
sudo apt-get install openjdk-6-jre-headless
If successful, an installer will launch, ask questions, and run for several minutes.

Alternatively, you may download and install the latest implementation of Java supported by Oracle. Read these step-by-step instructions for installing Java 6 on Ubuntu 10.04.
