I am on Ec2 with the base amazon ami linux- I have installed jenkins but when I go to pull the repo from github I am given the following error:

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

I have generated a key for the current user who installed jenkins and have managed to clone the repo using the git command line but jenkins can not.

I have copied the ~/.ssh files into /var/lib/jenkins/.ssh

I have added github to the known hosts and I have run out of solutions to try. Anyone know where I am going wrong? Is there a way to get jenkins to show the public key it's using and I can debug if it's using the correct one?

I removed the name of the repo because its a private repo

The error seems to be: host key verification failed.

You should log into your Jenkins host as the Jenkins user and run:

ssh [email protected]

Then answer yes to the prompt about the host key. This only needs to be done once.

Alternatively you could add "StrictHostKeyChecking no" to ~jenkins/.ssh/config.
