jenkins/hudson can't connect to github repo

Question

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:

Building in workspace /var/lib/jenkins/workspace/build social Checkout:build social / /var/lib/jenkins/workspace/build social - hudson.remoting.LocalChannel@5c7b21b Using strategy: Default Cloning the remote Git repository Cloning repository origin ERROR: Error cloning remote repo 'origin' : Could not clone [email protected]:adulion/.git hudson.plugins.git.GitException: Could not clone [email protected]:adulion/.git     at hudson.plugins.git.GitAPI.clone(GitAPI.java:245)     at hudson.plugins.git.GitSCM$2.invoke(GitSCM.java:1117)     at hudson.plugins.git.GitSCM$2.invoke(GitSCM.java:1059)     at hudson.FilePath.act(FilePath.java:832)     at hudson.FilePath.act(FilePath.java:814)     at hudson.plugins.git.GitSCM.checkout(GitSCM.java:1059)     at hudson.model.AbstractProject.checkout(AbstractProject.java:1218)     at hudson.model.AbstractBuild$AbstractRunner.checkout(AbstractBuild.java:581)     at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:470)     at hudson.model.Run.run(Run.java:1421)     at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46)     at hudson.model.ResourceController.execute(ResourceController.java:88)     at hudson.model.Executor.run(Executor.java:238) Caused by: hudson.plugins.git.GitException: Command "git clone --progress -o origin [email protected]:adulion/.git /var/lib/jenkins/workspace/build social" returned status code 128: stdout: Cloning into /var/lib/jenkins/workspace/build social...  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

Answer 1

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.
