Question

我在.ssh下具有默认密钥对，并在https://gitlab.com/profile/keys中添加了id_rsa.pub，但是仍然无法使用此密钥访问gitlab。

ssh -vT git@gitlab.com

无法登录：

无法克隆

git clone git@gitlab.com：denysobukhov / myprj

$ git clone git@gitlab.com:denysobukhov/myprj

我的配置

猫/ etc / ssh / ssh_config

$ cat /etc/ssh/ssh_config
Host *
    SendEnv LANG LC_*

将以下内容添加到空的〜/ .ssh / config中并没有帮助：

Host gitlab.com
    Hostname gitlab.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa

为什么我的钥匙不起作用？

Answer 1

最终找到了解决方案：生成了一个新的ED25519 SSH密钥对

ssh-keygen -t ed25519 -C "email@example.com"

，并将以下内容添加到〜/ .ssh / config中：

Host gitlab.com
  Hostname altssh.gitlab.com
  User git
  Port 443
  PreferredAuthentications publickey

还证实〜/ .ssh / config的修改是决定性的。

Answer 2

我在尝试从私人 GitLab 存储库推送/拉取时遇到了类似的问题（通过 Google 发现的）。

git 存储库已使用 HTTPS 克隆，例如https://gitlab.com/user/repo.git，在设置任何 SSH 密钥之前。

为了将 SSH 身份验证用于拉取/推送，即使在 GitLab 设置中设置了 SSH 密钥后，远程 URL 也必须更改为 SSH 版本 git@gitlab.com:user/repo.git。

git remote set-url origin git@gitlab.com:user/repo.git

（假设你的遥控器叫做 origin。）

这可能只是必要的，但还不够，因为我尝试了很多其他的东西，而当它们自己不起作用时却没有重置更改。

无法使用ssh密钥克隆Gitlab私有存储库。密钥验证不起作用
