Jenkins: Failed to connect to repository

git, github, jenkins, ssh

Solution

The problem was that somehow I created the ssh files with the root user. So the files owner was root.

The solution was just change the ownership to the jenkins user.

chown jenkins id_rsa.pub 
chown jenkins id_rsa

Problem

I'm trying to connect jenkins on a github repo. When I specify the Repo URL jenkins return the following error message: Failed to connect to repository : Command "git ls-remote -h git@github.com:adolfosrs/jenkins-test.git HEAD" returned status code 128: stdout: stderr: Host key verification failed. fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. When using the HTTPS:// Url jenkins returns: Failed to connect to repository : Failed to connect to https://github.com/adolfosrs/jenkins-test.git (status = 407) I could successfully clone the repo at the same machine where jenkins is running and I also run the `git ls-remote -h git@github.com:adolfosrs/jenkins-test.git HEAD` command. So I have the right SSH at github.
