Install a sample Android app from the Chrome Store to get the runtime. Test out that app, make sure it runs on your hardware. Ubuntu might need sudo apt-get install lib32stdc++6. Install Node.js and install the tool (might need a sudo prefix). With Chrome 38+ you can now side load as many applications as you want. If you have older apps that were created using chromeos-apk tool then re-convert them or remove the "key" option from manifest.json.
