Platform Version

Ubuntu 18.04

Replication Case

I am running below command.

knife bootstrap <ip-address> -N vj-test-ssh -c ~/workspace/chef-repo/.chef/knife.rb --ssh-identity-file ~/.ssh/id_rsa --sudo -VV --yes

Client Output

Stacktrace

@Vasu1105 I tried to reproduce the issue but seems it is working as expected in latest chef infra 15.0.301 build.

Also with build 15.0.253 it working as expected. please have a look at logs:

@vsingh-msys I verified it with 15.0.300 and not yet released version 15.0.301 issue still exist for me.

What I see the problem here it behaves differently for the same scenarios. What I debug and understood is if --connection-user is not provided it uses root user to ssh the system. And it fails where login with root user is not enabled. The weird thing it gives different error for @vsingh-msys.

In Chef-14 it notifies user to use the specific login user rather than error out.

I accidentally reproduced this testing knife-ec2 without passing -x ubuntu.

notice we are connecting as root but the ec2 ubuntu images have ubuntu as the administrator login.
