我已经在 NUC 上安装了 Ubuntu Core (ubuntu-core-22-amd64.img.xz)。使用以下说明：https://ubuntu.com/core/docs/install-nuc。
当我看到类似于成功启动服务器时的屏幕时，我无法通过 ssh 登录。
我已经创建了我的 Ubuntu One 帐户。并加载了一个公钥（没有密码）。我甚至使用上面的教程启动了两个 VirtualBox 实例。并且能够使用我的 Ubuntu 帐户上的公钥通过 SSH 连接到两个虚拟机。
这是我尝试 ssh 到物理 NUC（而不是 VM）时得到的结果。与 VM 一样，我可以成功 ssh 进入。
ssh -vvvvvvvv -i ~/.ssh/id_rsa_ubuntu_core [email protected]
