I have installed Ubuntu Core (ubuntu-core-22-amd64.img.xz) on a NUC. Using these instructions: https://ubuntu.com/core/docs/install-nuc.
When I get the screen, which is similar to when I have successfully booted a server. I am unable to ssh in.
I have created my Ubuntu One account. And loaded a public key (which does not have a passphrase). I went as far as to spin up two VirtualBox instances using the tutorial above. And was able to SSH to both VMs with the public key on my Ubuntu account.
Here is what I get when attempting to ssh to the physical NUC, not the VM. As with the VMs I can successfully ssh in.
ssh -vvvvvvvv -i ~/.ssh/id_rsa_ubuntu_core [email protected]
