Version 5 installation error

[kallolkk]

Hi Sonata Dev Team,
I am trying to deploy sonata (5) on ubuntu server 18.04. I went through the following steps:
s1: I installed all the dependencies.
s2: created a used tango.
s3: cloned the tng-devops.
s4: I tried to deploy sp using sudo ansible-playbook roles/sp.yml -i environments -e target=localhost --ask-vaultpass and i am getting the follwoing error.

Begenning part of the error message. I believe it has something to do with the host (to be specific host_list).

Please help me to solve the error.

Best Regards
Kallol
