Setting 700 to .ssh and 600 to authorized_keys solved the issue.

chmod 700 /root/.ssh
chmod 600 /root/.ssh/authorized_keys

    wondering, how do you know it solv**ed**the issue? :) – P.... Jun 09 '22 at 15:40
  • your Jenkins output shows a permission denied error, which is related to file permission. just try to update the permission. and check again. – Abhishek Patwa Jun 09 '22 at 15:42
  • I think the OP is trying to `scp` through the user `younes`. In the `scp` command he has not used `-i ` that caused the `permission denied`. Based on the logs, the private keys are copied to `/var/lib/jenkins` but he did not provide it `scp`. – P.... Jun 09 '22 at 15:55
  • Also, the error for permissions(`group/world readable`) would generate different errors(feel free to reproduce in your machine). Not the error shown In the logs. So, **perhaps the answer is not correct.** . (happy to be corrected) – P.... Jun 09 '22 at 15:57
