I’ve just burned the latests RPi image 16.04LTS onto a 32GB card and booted up with RPi 3B. It loads up to the splash screen (mate logo with 5 dots flashing green underneath ), and it gets stuck there. I’ve tried it a few times, re-downloaded the image, changed PSU etc etc. Any ideas? I’d really like to try Ubuntu mate but doesn’t give me much confidence…
Have patience! Have you checked the sha256sum of the downloaded file (not the .img)? Have you checked the condition of the uSD card with hwtest2 or f3read/f3write? What burning software are you using…on what platform?
Actually I have the same issue but after all the config steps. If you find a way please share it with us
