actually, the host OS for this post is a ubuntu 18.04.2 server image.

root@pi:~# cat /etc/issue.net

Ubuntu 18.04.2 LTS

root@pi:~# uname -a

Linux pi 4.19.57-v8+ #2 SMP PREEMPT Tue Jul 9 20:31:37 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux

root@pi:~# file /bin/ls

/bin/ls: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-, for GNU/Linux 3.7.0, BuildID[sha1]=de05fcef79d88af9cf9a71ed38e73af0b179bfb2, stripped

Wait - what did it take to get 18.04.2 server running?

Is there an SD image that works?

Ubuntu Mate has an image that works on the Pi3.

baking one right now -- it is based on http://cdimage.ubuntu.com/ubuntu/releases/18.04.2/release/ub... but slightly modified (no root password, KVM setup, docker installed etc.)

will provide a link once I manage to upload it somewhere

there you go: https://cloudkernels.net/rpi4-64-bit-kvm-docker.img.xz sha1sum: 1b96a6be5256182eaceb5894fb993c8ffce8c2a2

it's quite beefy, 2.5GB -- apologies for that. We should be able to craft a much smaller image based on the ubuntu server release. Apparently, something was off about mounting the root partition on the first boot, so we went with our original image.

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...

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.

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 root@192.168.178.184's password: Permission denied, please try again. root@192.168.178.184's password: Permission denied, please try again. root@192.168.178.184's password: root@192.168.178.184: Permission denied (publickey,password).

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.)
