我遵循了github手册Generating SSH keys，但我有以下输出：
$ ssh -Tv git@github.com

archlinux ~/.ssh/config为空，我的/etc/ssh/sshd_config有默认配置。另外，我有以下文件：
$ ls -al ~/.ssh
total 16K
drwx------ 2 juan users 4.0K may 8 11:42 ./
drwxr-xr-x 75 juan users 4.0K may 8 11:45 ../
-rw------- 1 juan users 1.7K may 7 23:22 id_rsa
-rw-r--r-- 1 juan users 403 may 7 23:22 id_rsa.pub
当我这样做时，我会得到与预期不同的东西。
$ ssh-add -l
2048 SHA256:KWw15AkdJnqJ3dZQ+t8uEdLoBpIlj0ELtgH1K7GWC1c /home/juan/.ssh/id_rsa (RSA)
我已经问过，但我不知道为什么我被否决了。拜托，我真的迷路了，因为我无法通过https推动而且我是新手。
