当运行尝试连接到 github 时，我得到以下信息：
$ ssh -T [email protected]
Permission denied (publickey).
这是我对该目录的权限：
$ ls -la ~/.ssh
total 24
drwxr-xr-x 2 ec2-user ec2-user 120 Nov 23 23:21 .
drwx------ 9 ec2-user ec2-user 214 Nov 23 23:21 ..
-rw-r--r-- 1 ec2-user ec2-user 393 Nov 23 19:19 authorized_keys
-rw------- 1 ec2-user ec2-user 419 Nov 23 23:07 id_ed25519
-rw-r--r-- 1 ec2-user ec2-user 106 Nov 23 23:10 id_ed25519.pub
-rw------- 1 ec2-user ec2-user 3243 Nov 23 19:42 id_rsa
-rw------- 1 ec2-user ec2-user 750 Nov 23 19:43 id_rsa.pub
-rw------- 1 ec2-user ec2-user 2375 Nov 23 21:02 known_hosts
然后运行详细：
$ ssh -vT [email protected]

这里似乎存在权限问题，但我不太确定。任何帮助将不胜感激。
