A nice experiment made by wxl from the Lubuntu QA Team: running Lubuntu Xenial Xerus on a Raspberry Pi 2, with LXQt desktop. Made with Ubuntu Pi Flavour Maker, and following simple instructions:

Get the image from here

Install the image

do-release-upgrade to Xenial

Install LXQt packages following the wiki guide

And that’s all. Enjoy Lubuntu in your new Pi. Remember this is just an experiment, it may be unstable. But what are Raspberry Pi computers for, but testing and having fun?
