我完全按照这里的指南进行操作：https://docs.gitlab.com/ee/user/ssh.html#add-an-ssh-key-to-your-gitlab-account到信中。由于某种原因，我仍然无法 ssh 到实例...
这是

当前的情况是这样的：我的 .ssh 目录中有多个密钥，其中多个密钥现在已添加到 git lab 中的 ssh 密钥中。但它们似乎都不起作用。我还有以下配置文件：
Host gitlab.instance.ch
PreferredAuthentications publickey
IdentityFile /afs/instance.ch/user/l/username/.ssh/id_ed25519
我觉得这应该很简单，所以我不确定出了什么问题。任何帮助/建议将不胜感激干杯
尝试添加多个密钥、更改配置、重新启动电脑，但什么也没有
我将首先使用新密钥进行测试，无需密码短语，并使用更简单的加密算法
ssh-keygen -t rsa -P "" -f ~/.ssh/newKey
将
~/.ssh/newKey.pubssh -i ~/.ssh/newKey -T [email protected]
