I have a MATE 15.10 running on my Raspberry Pi2 but even after all the updates it won't boot on Raspberry Pi3.
Has anyone successfully updated and/or can suggest the steps needed.
Doing a re-install and restore all settings seems like a lot of work.
UPDATE
I decided to try rpi-update, which updated the kernel to Linux PiUbuntu 4.1.20-v7+
This works on both Pi2 and Pi3.
Unfortunately the inbuilt WiFi on the Pi3 is not found.
The following (cryptic) startup messages resulted.
[Fri Mar 25 12:11:41 2016] systemd[1]: Started udev Coldplug all Devices.
[Fri Mar 25 12:11:42 2016] systemd[1]: systemd-modules-load.service: Main process exited, code=exited, status=1/FAILURE

[Fri Mar 25 12:11:42 2016] systemd[1]: systemd-modules-load.service: Failed with result 'exit-code'.
I finally resolved this by downloading firmware.
