Codebook for Windows can run on Linux using Wine.
Run this command to download and run the script to install Wine, Codebook and the required prerequisites.
curl -s https://www.zetetic.net/downloads/codebook/windows/wine/codebook-wine.bash | bash
This command should start the process to install wine and all the necessary dependencies. It may take a really long time to run because it has to download and install software in the background. At the end of the process you should see the window for the Codebook installer, which you can run through to finish the installation.
For most distributions a Codebook program should automatically be added by Wine to the application launcher.
