我尝试了一切可以在网上找到的东西。很抱歉，如果它看起来像重复的答案，我随处可见，它没有帮助我解决问题。我正在尝试为git设置SSH访问权限，我创建并添加了一个git的密钥。
dummy@dummy:~/.ssh$ ssh-add -l -E md5
4096 MD5:fc:53:c6***e:e5:2b:f9 id_rsa (RSA)
dummy@dummy:~/.ssh$ ssh-add -l
4096 SHA256:3qSYSF7****0D3qJLO3PAII0 id_rsa (RSA)
dummy@dummy:~/.ssh$ eval "$(ssh-agent -s)"
Agent pid 11388
dummy@dummy:~/.ssh$ ssh -vT git@github.com

所以没有任何作用.. 我的权限：
drwx------ 2 dummy dum 4.0K Jun 11 13:59 .
drwxr-xr-x 4 dummy dum 4.0K Jun 11 14:20 ..
-rw------- 1 dummy dum 3.2K Jun 11 13:47 id_rsa
-rw-r--r-- 1 dummy dum 744 Jun 11 13:47 id_rsa.pub
我做了
ssh-add ~/.ssh/id_rsa
以及我能找到的其他一切。
我从id-rsa.pub复制了密钥并添加到git ssh。保存它。
可能有什么问题???
