You’ll need a microSD card which is 8GB or greater to fit the image. The file system can be resized to occupy the unallocated space of the microSD card, on Ubuntu MATE 16.04 this can be done via Ubuntu MATE Welcome.
NOTE! There are no predefined user accounts. The first time you boot one of the desktop images it will run through a setup wizard where you can create your own user account and configure your regional settings. The first boot is quite slow but, once the first boot configuration is complete, subsequent boots are much quicker.
- During first boot configuration Ubiquity does not prompt to join available WiFi networks.
- Upon completion of the first boot setup WiFi doesn’t work, at all. Reboot and WiFi will be available.
Both these issues will be addressed in Ubuntu MATE 16.04.1 for Raspberry Pi 2 and 3 which is due in late July.
