BitBucket: Host key verification failed
GitAuthenticationSshBitbucketGit Problem Overview
I want to clone a remote repository to my local machine. I used the command:
git clone [email protected]:<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?

Solution 1 - Git
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:
-
Run
ssh bitbucket.org
-
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)?
-
You verify the fingerprint in the prompt is the same as on the bitbucket website:
SHA256:zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojez9YXaGp1A bitbucket.org (RSA)
-
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.
Solution 2 - Git
mkdir ~/.ssh
touch ~/.ssh/known_hosts
ssh-keyscan bitbucket.org >> ~/.ssh/known_hosts
Solution 3 - Git
-
Create a file named
known_hosts
inside~/.ssh
if it doesn't already exists. -
Paste the following into it and you're good to go.
bitbucket.org,104.192.143.1 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAubiN81eDcafrgMeLzaFPsw2kNvEcqTKl/VqLat/MaB33pZy0y3rJZtnqwR2qOOvbwKZYKiEO1O6VqNEBxKvJJelCq0dTXWT5pbO2gDXC6h6QDXCaHo6pOHGPUy+YBaGQRGuSusMEASYiWunYN0vCAI8QaXnWMXNMdFP3jHAJH0eDsoiGnLPBlBp4TNm6rYI74nMzgz3B9IikW4WVK+dc8KZJZWYjAuORU3jc1c/NPskD2ASinf8v3xnfXeukU0sJ5N6m5E8VLjObPEO+mN2t/FZTMZLiFqPWc/ALSqnMnnhwrNi2rbfg/rd/IpL8Le3pSBne8+seeFVBoGqzHM9yXw==
Solution 4 - Git
You'll get the same error:
Host key verification failed.
in case you press enter instead of answering the question:
Are you sure you want to continue connecting (yes/no/[fingerprint])?
with yes
Solution 5 - Git
If you already have ssh enabled do copy all the files from .ssh folder inside backup folder before following steps
- Open Git Bash and type ssh-keygen, and press Enter three times (one for location, and two for empty passphrase).
- It will create .ssh folder if not present and creates two files id_rsa & id_rsa.pub inside .ssh folder.
- Now go to Bitbucket settings -> ssh keys -> aad key
- Paste id_rsa.pub string in Bitbucket and press ok.
- Restart Git Bash
- Try to clone repo. It should work now.
