Ubuntu MATE 15.04 Raspberry Pi 2

Ubuntu MATE for the Raspberry Pi 2
Rohith Madhavan has made an Ubuntu MATE 15.04 image for the Raspberry Pi 2 which you can download or build yourself.

The image is functional and based on the regular Ubuntu armhf base, and not the new Snappy Core, which means that the installation procedure for applications is the same as that for the regular desktop version, ie using apt-get.

We have done what we can to optimise the build for the Raspberry Pi 2 and one can comfortably use applications such as LibreOffice, which in fact is a joy to use :-) But the microSDHC I/O throughput is a bottleneck so we recommend that you use a Class 6 or Class 10 microSDHC card. If you build the image yourself we recommend you use the f2fs filesystem.



You'll need a microSD card which is 4GB or greater to fit the image. The file system can be resized to occupy the unallocated space of the microSD card, similar to Raspbian.
