Pedro Dias Vicente, a senior XDA member, posted news on the Ubuntu Touch mailing list informing developers and users alike about his attempt of porting Canonical's mobile operating system to the Sony Xperia Z Ultra smartphone.

Those of you interested in installing the Ubuntu Touch OS (also known as Ubuntu for Phones) on the Sony Xperia Z Ultra device are invited to visit the port's XDA forum page, where they can find the latest images of Ubuntu Touch 15.04 (Vivid Velvet) which they can flash on their smartphones using the instructions provided by the developer.

"I got the Ubuntu touch working through the adb root then adb shell," says Pedro Dias Vicente. "I will release the new images for Sony Z Ultra fastboot mode very soon. I will update the device folder to do the upper code for compliant and howto fix dtb boot.img fastboot. Please reply the issues even the working stuff here on this topic."

Sony Z Ultra is an Android-powered phone that was released sometime in June 2013, boasting a huge 6.4-inch screen with a FullHD 1080x1920 resolution, a Quad-core 2.2 GHz Krait 400 processor, an Adreno 330 GPU, an 8MP rear camera, a 2MP front camera, and a non-removable Li-Ion 3050 mAh battery.

By default, the smartphone comes with Android 4.2 (Jelly Bean) mobile operating system, which has been highly customized by Sony. Of course, users can upgrade the OS to Android 5.1 (Lollipop), one of the latest stable and most advanced versions of Google's mobile OS.
