所以我从网上转移我的实例，下载一个安装它的密钥对，一切都很好。 然后我重新启动了我的电脑，我无法再SSH进入。 我试着redownloading一个密钥对并重新安装它，但我不断获得权限被拒绝（publickey）错误。
这是详细的输出（我尝试使用-i / path / to / keypair选项以及没有运气）：

我在那个日志中看到的唯一的事情是不允许漫游你的密钥是1还是2？
还要检查/Users/tigger/.ssh目录中的权限，该目录应该由用户拥有，并且是chmod 700. authorized_keys文件也应该是chmod 700，并由用户拥有。
你是否试图用正确的用户login？ 例如，Ubuntu镜像使用ubuntu用户而不是root用户。
