我无法从 WSL2 默认 Ubuntu 安装连接到 RPi Ubuntu Core 22 20220610.2。下载链接（以及任何其他 Ubuntu 版本）。它一直要求我输入密码。密码应该是什么？
john@LAPTOP-LUVS8UFH:~$ ssh [email protected]

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

我记得我之前可以连接，但我不明白我该怎么做才能触发密码提示。此外，在 RPi 上重新安装 Ubuntu Core 22 也没有改变任何东西。
- 是的，我在主目录中生成的所有公钥都
ssh-keygen添加到了 Ubuntu One。我 - 我从主目录和 .ssh 目录直接运行 ssh 命令 - 行为相同。我还尝试了此命令并提供我的私钥：
ssh -i id_rsa [email protected] - 我甚至在 WSL 上创建了一个新的 Ubuntu 20。但是没有运气。
有什么提示吗？

将 Ubuntu Core 22 64Bit 直接从 Raspberry Pi Imager 软件写入 RPi 后，它就起作用了。见图。不知道为什么这两个版本会有所不同。
答案1
我一直被同样的事情困扰。
可行的解决方案是
- 将 ssh-key 添加到帐户
- 对 ubuntu 核心进行全新安装。
我不明白为什么它这么笨。我不明白为什么我没有在设备上进行任何身份验证，而只是输入 ID（电子邮件）。但这样它就起作用了。
注意，我以前使用 ed25519 密钥，但这里我按照建议使用了 rsa无法在 ubuntu core 22 上登录 ssh. 带有 id 的注释（ubuntu-one 中的电子邮件）。
我不确定这是否重要:)
