Comment 30 for bug 1263811

I got mine working. Here's what I did on my unlocked Nexus 4.

Here are the steps I took:

1) Re-flash everything back to stock Android 4.4.2, KOT49H.

2) Enable USB debugging.

3) Download dualboot.sh and run ./dualboot.sh FULL

4) Open the Ubuntu Dual Boot app, download the Ubuntu image and let it do its thing.

5) Reboot to Ubuntu. Done.

*Note:
I did not install any recovery or SuperUser app after I re-flashed.

Everything feels great. I love the interface. It does get laggy and buggy at times but everything else is working (like calling, SMS, mobile data & camera) except WiFi. Navigating in it is quite natural to me except I find it quite hard to go "Back" to the previous intent/window, I have to swipe down from outside screen OR touch somewhere around the bottom area.
