on the first run you have to execute the playbook "common_first.yml" This HAS TO BE DONE so that all users and ssh-keys are deployed so you can administrate the server effectively.

set the following for the first run

Create inventory group 'common_first' - also check that your hosts are reachable via network. If they are reachable via external, dont forget to set your ansible_port
Enter the hostname of your server/client
run the playbook
remove the server/client from the inventory group
reboot the server/client so the hostname is overwritten
