Ok, so I must be a bit thicker than the rest, but what's the login? I tried ubuntu with no password, as well as root with no password, as well as root/root, and root/admin, and the default pi/raspberry, but to no avail.

What am I missing here?

hmm I'm pretty sure its root with no password... you can edit /etc/shadow and remove the 2nd field on root and ubuntu and try again just in case

I just tried root with no password, didn't work for me. I am getting bounced. Rewriting the SD card one more time...

Ok, so I am deeply confused. DOwnloaded the image, the SHA1sum is correct. Unpacked the image, wrote it on an 32GB SD card from Samsung. I am booting from an RPI4 with 4GB of RAM. Are the 4GBs the issue? I can ssh to it, it will send me its public key, and I can give the login and the password, but providing "root" as login and hitting enter upon the password gives me this:

C:\Windows\System32>ssh -l root 192.168.178.184 [email protected]'s password: Permission denied, please try again. [email protected]'s password: Permission denied, please try again. [email protected]'s password: [email protected]: Permission denied (publickey,password).

root w/o password won't work for me. How is anyone else connecting? I am using SSH.

password-less SSH is not supposed to work, use a console cable or just inject your SSH key to /root/.ssh/authorized_keys and it should work.

built a stock ubuntu (cloud-init ready) image: https://cloudkernels.net/ubuntu-18.04.2-preinstalled-server-... sha1sum: 0b1d8b72ea5410fb7928925fd76dd0218b4f7a94

The behaviour should be identical to installing on a RPi3 (user/pass ubuntu/ubuntu, ethernet networking setup correctly etc.)
