Ubuntu – Configuring jenkins with bitbucket error

hudsonJenkinsUbuntu

I've got an ssh key in ~/.ssh/id_rsa.pub when I login as the jenkins user.

I've imported this into bitbucket correctly and it has accepted the key.

When I try to do a git clone (to the correct URL) I still get….

stderr: Host key verification failed.
fatal: The remote end hung up unexpectedly

Does anyone know of a reason why this would occur? According to the documentation I've read ~/.ssh is the correct directory as the jenkins user for this file to exist.

EDIT : My jenkins user does not have a known_hosts file in ~/.ssh but my root level ones do – should it? I can do a clone with my jenkins user just fine and it doesn't mention the host at all as jenkins user.

Best Answer

You should have the private key there, not just the public key. If your public key is id_rsa.pub, your private key is probably named id_rsa.

I assume you copied this public key from some other system (perhaps your local desktop)?

You can either copy the corresponding private key to the jenkins ~/.ssh directory as well, or you can generate a new keypair for your jenkins user and import that public key in bitbucket.

To generate a new ssh keypair:

cd ~/.ssh
ssh-keygen -t rsa

This will generate the following output:

Generating public/private rsa key pair.
Enter file in which to save the key (/home/b/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/jenkins/.ssh/id_rsa.
Your public key has been saved in /home/jenkins/.ssh/id_rsa.pub.
