让我也分享一下我的经验，

我试图从Gerrit回购中克隆一些项目，我在帐户设置中获得了我的公钥。

在第一次尝试克隆git时，我得到了以下错误:

Unable to negotiate with XX.XX.XX.XX port XXX: no matching key exchange
method found. Their offer: diffie-hellman-group1-sha1

我发现我需要通过SSH选项-oKexAlgorithms=+diffie-hellman-group1-sha1以某种方式来git克隆。

希望GIT_SSH_COMMAND环境变量完成了这项工作:

export GIT_SSH_COMMAND="ssh -oKexAlgorithms=+diffie-hellman-group1-sha1"

但是git克隆仍然没有开始工作。现在它抛出(关于主题):

Permission denied (publickey).

我已经得到SSH密钥，不想重新生成它们。我检查了普通的SSH连接到主机，它是ok的:

****    Welcome to Gerrit Code Review    ****

  Hi XXXXX, you have successfully connected over SSH.

  Unfortunately, interactive shells are disabled.
  To clone a hosted Git repository, use:

  git clone ssh://xxxxx@xx.xx.xx:xxx/REPOSITORY_NAME.git

我有点困惑。我重新开始并通过-vvv选项打开SSH的调试。我看到了下面这些:

debug1: read_passphrase: can't open /dev/tty: No such device or address

可能，这是GIT_SSH_COMMAND env变量的开销-我的密钥是用passphrase保护的(我在检查登录到git repo主机时输入了它)。

所以，我决定去掉这个短语。一个简单的命令帮助了我:

ssh-keygen -p

然后，我输入了我的“旧密码”的密码短语，并在“新密码”上按了两次ENTER键，让它空着，即根本没有密码短语，并确认我的选择。

之后，我在本地磁盘上获得了新克隆的回购。

我正与同样的问题作斗争，这就是我所做的，我能够克隆回购。我在Mac上遵循了这个步骤。

第一步:检查我们是否已经拥有公共SSH密钥。

打开终端。 输入ls -al ~/。查看是否存在现有的ssh密钥:

检查目录列表，查看是否已经拥有公共SSH密钥。默认public是以下d_dsa之一。酒吧,id_ecdsa。酒吧,id_ed25519。酒吧,id_rsa . pub。

如果你没有找到，那么转到步骤2，否则继续步骤3

步骤2:生成SSH公钥

Open Terminal. Enter the following command with a valid email address that you use for github ssh-keygen -t rsa -b 4096 -C "your_email@example.com" You will see the following in your terminal Generating public/private rsa key pair. When it prompts to"Enter a file in which to save the key," press Enter. This accepts the default file location. When it prompts to Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter] Just press enter again. At the prompt, "Type a secure passphrase. Enter passphrase (empty for no passphrase): [Type a passphrase]" press enter if you don't want to Enter same passphrase again: [Type passphrase again] press enter again

这将生成id_rsa.pub

步骤3:添加SSH密钥到SSH -agent

Interminal type eval "$(ssh-agent -s)" Add your SSH key to the ssh-agent. If you are using an existing SSH key rather than generating a new SSH key, you'll need to replace id_rsa in the command with the name of your existing private key file. Enter this command $ ssh-add -K ~/.ssh/id_rsa Now copy the SSH key and also add it to you github account In terminal enter this command with your ssh file name pbcopy < ~/.ssh/id_rsa.pub This will copy the file to your clipboard Now open you github account Go to Settings > SSH and GPG keys > New SSH key Enter title and paste the key from clipboard and save it. Voila you're done.

我删除了node_modules/ package-lock。Json和yarn。锁文件。再次运行npm i。这为我解决了问题。

如果用户未生成之前设置的ssh公私钥对

此信息在聊天上工作，但可以应用于所有其他支持SSH pubkey身份验证的git存储库。(参见[gitolite][1]， gitlab或github。)

首先设置您自己的公钥/私钥对集。这 可以使用DSA或RSA，所以基本上你设置的任何密钥都可以工作。 在大多数系统上，您可以使用ssh-keygen。

First you'll want to cd into your .ssh directory. Open up the terminal and run: cd ~/.ssh && ssh-keygen Next you need to copy this to your clipboard. On OS X run: cat id_rsa.pub | pbcopy On Linux run: cat id_rsa.pub | xclip On Windows (via Cygwin/Git Bash) run: cat id_rsa.pub | clip On Windows (Powershell) run: Get-Content id_rsa.pub | Set-Clipboard (Thx to @orion elenzil) Add your key to your account via the website. Finally setup your .gitconfig. git config --global user.name "bob" git config --global user.email bob@... (don't forget to restart your command line to make sure the config is reloaded) That's it you should be good to clone and checkout.

如果用户已经生成了之前设置的ssh公私钥对

检查哪个密钥已被授权在您的github或gitlab帐户设置 确定必须从本地计算机关联哪个相应的私钥

Eval $(ssh agent -s)

定义键的位置

ssh-add ~ / . ssh / id_rsa

我必须将ssh密钥复制到根文件夹。 谷歌云计算引擎，Ubuntu 18.04

sudo cp ~/.ssh/* /root/.ssh/

我也犯了同样的错误。

问题是，当将公钥复制到BitBucket(在我的情况下)时，在末尾复制/粘贴了一个不可见的换行符。

因此，在复制公钥时，首先将其复制到记事本，删除末尾的空行，复制并粘贴。
