Jenkins failing to fetch private repo from GitHub

Question

I've been banging my head for hours now...

This error isn't budging. For the record:

1. I tried: login jenkins in terminal, and that command displayed in red works.
2. While logged in as jenkins, I can clone the repo without problems.
3. The SSH keys are in place, and they show up in the ssh-add -l
4. The known_hosts file is properly configured
5. I already ssh'd into github.com to add it in known_hosts
6. Replacing the "Repository URL" with a public repo https://github.com/... works.
7. I pulled out most of my hair, and there are a few left...

What do I suspect being the problem?

When I copied the generated SSH key that I have in ~jenkins/.ssh/id_rsa.pub, I noticed that in the end of the key, it reads: root@MyComputer, not jenkins... Because I had to use sudo ssh-keygen to generate the key... Is that bad?

Here is the build log for completeness:

Answer 1

It might be a plugin issue too as found by this SO user. I kind of verified it too, although, I used https and not the git protocol. If I run

git clone https://blah.com:8443/blah.git

from a shell, it works. If I run it inside Jenkins under the

Build>Execute shell>Command, that also works. It's just when I enter that url in the

Source Code Management>Git>Repository URL box that it doesn't work.

Answer 2

I solved this problem on OSX by changing Jenkins startup from launchdaemons to launchagents, hope this works for you.
