Ssh 权限被拒绝（公钥、gssapi密钥、gssapi带麦克风）。断开连接

当我要使用以下命令将文件从本地计算机传输到服务器时：

scp-i/home/user/.ssh/id\u rsa/home/user/fileuser@extension：/home/user/

警告：标识文件/home/user/.ssh/id\u rsa不可访问：没有此类文件或目录。权限被拒绝（公钥、gssapi密钥、gssapi带麦克风）。断开连接

` 文件/home/user/.ssh/id\u rsa存在，我不知道为什么它不能识别它

我使用chmod进行了一些权限更改，但没有结果。我很沮丧

我显示命令

-ssh user

，以便他们可以看到任何可能的错误
