I just used win32 disk imager to put Lubuntu on my SD card, which I then plugged into my orange pi zero. The orange pi zero has no video out, so you have to ssh into it. I downloaded it from the orange pi website.
I have successfully SSH'd in, and am at the point where it asks me to login. I type in root, and I have tried many passwords, and I don't know which is correct, I keep getting "Access Denied".
