IcedTea plugin for OpenJDK 8
At the moment, icedtea-8-plugin is not available in the official Ubuntu repositories. Maarten Fonville offers a PPA repository with a working icedtea-8-plugin package.
sudo add-apt-repository ppa:maarten-fonville/ppa
sudo apt-get update
sudo apt-get install icedtea-8-plugin

If you're using Ubuntu 14.04 (for which openjdk-8-jre is not yet backported), then for the time being the OpenJDK ppa must be added first:
sudo apt-add-repository ppa:openjdk-r/ppa
Recent versions of Chrome do not support the Java plugin (cf. How do I get Java plugin working on Google Chrome?).
The file you want to install is icedtea-plugin. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:
