Unable to clone repository to jenkins on linux

Question

I am able to clone a repository that i've created for one of my jobs on jenkins. Whereas, cloning a repository which is a fork of another repository gives the following error when trying to build it - Any suggestions on what could be the problem?

Answer 1

My first guess would be that the user jenkins is running as does not have permission to access the git repo.

I would try logging into the server and running

sudo su <jenkins_user_name>
git clone https://.....

You may just need to add the server to your known hosts if the SSH Keys are already setup.
