主机密钥验证失败。

没有关于身份验证，所以您正在处理错误的字段。这意味着bitbucket.org 的主机密钥不在您的〜/ .ssh / known_hosts 中，您的客户端没有任何方式验证它。 已经回答了很多次如何解决它，但是如何正确地做到这一点？

section 。因此：
$ b

1. 运行 ssh bitbucket.org

它会提示你一个指纹：



 主机的真实性'bitbucket.org（104.192 .143.3）'不能建立。 
 RSA密钥指纹是SHA256：*****。 
您确定要继续连接（是/否）吗？ 
 




2. 验证提示中的指纹与 bitbucket网站：
   
   

    SHA256：zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojez9YXaGp1A bitbucket.org（RSA）
   




3. 您写是，然后按回车确认连接是否正常。

或者只需从 bitbucket网站直接在〜/ .ssh / known_hosts 文件中

  echo bitbucket.org，104.192.143.1 SSH-RSA AAAAB3NzaC1yc2EAAAABIwAAAQEAubiN81eDcafrgMeLzaFPsw2kNvEcqTKl / VqLat / MaB33pZy0y3rJZtnqwR2qOOvbwKZYKiEO1O6VqNEBxKvJJelCq0dTXWT5pbO2gDXC6h6QDXCaHo6pOHGPUy + YBaGQRGuSusMEASYiWunYN0vCAI8QaXnWMXNMdFP3jHAJH0eDsoiGnLPBlBp4TNm6 rYI74nMzgz3B9IikW4WVK + dc8KZJZWYjAuORU3jc1c / NPskD2ASinf8v3xnfXeukU0sJ5N6m5E8VLjObPEO + mN2t / FZTMZLiFqPWc / ALSqnMnnhwrNi2rbfg / rd / IpL8Le3pSBne8 + seeFVBoGqzHM9yXw ==>> 〜/ .ssh / known_hosts

I want to clone a remote repository to my local machine. I used the command:

git clone git@bitbucket.org:<username>/<repo_name>.git

and I got the message:

The authenticity of host 'bitbucket.org (104.192.143.3)' can't be
established. RSA key fingerprint is
SHA256:****. Are you sure you
want to continue connecting (yes/no)?  Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository
exists.

I just want to mention that I already took care of the ssh issues. I generated an ssh key by the command 'ssh-keygen' and I copied the contents of ~/.ssh/id_rsa.pub to Bitbucket Settings -> SSH keys (according to this link: https://confluence.atlassian.com/bitbucket/set-up-ssh-for-git-728138079.html)

I also looked at my "user and group access" and I saw this:

Can you advise me what to do?

The message says

Host key verification failed.

nothing about authentication, so you are working on the wrong field. It means that the host key of the bitbucket.org is not in your ~/.ssh/known_hosts and your client does not have any way how to verify it. It was answered many times how to workaround it, but how to do it properly?

There is section in the bitbucket manuals, describing how their public keys and fingerprint looks like. So:

1. Run ssh bitbucket.org

2. It will prompt you with one of the fingerprints:

   The authenticity of host 'bitbucket.org (104.192.143.3)' can't be established.
   RSA key fingerprint is SHA256:*****.
   Are you sure you want to continue connecting (yes/no)?
   

3. You verify the fingerprint in the prompt is the same as on the bitbucket website:

   SHA256:zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojez9YXaGp1A bitbucket.org (RSA)
   

4. You write yes and press enter to verify the connection works.

Or just copy the public key from the bitbucket website directly in the ~/.ssh/known_hosts file

echo "bitbucket.org,104.192.143.1 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAubiN81eDcafrgMeLzaFPsw2kNvEcqTKl/VqLat/MaB33pZy0y3rJZtnqwR2qOOvbwKZYKiEO1O6VqNEBxKvJJelCq0dTXWT5pbO2gDXC6h6QDXCaHo6pOHGPUy+YBaGQRGuSusMEASYiWunYN0vCAI8QaXnWMXNMdFP3jHAJH0eDsoiGnLPBlBp4TNm6rYI74nMzgz3B9IikW4WVK+dc8KZJZWYjAuORU3jc1c/NPskD2ASinf8v3xnfXeukU0sJ5N6m5E8VLjObPEO+mN2t/FZTMZLiFqPWc/ALSqnMnnhwrNi2rbfg/rd/IpL8Le3pSBne8+seeFVBoGqzHM9yXw==" >> ~/.ssh/known_hosts

if nothing from the above helps, please run ssh -vvv bitbucket.org and post the output to the edited question.
