PostgreSQL version: 12.0
Operating system: Kali Linux
Description:

I try to initiate PostgreSQL
when I do this, it shows it is all good until the end and says host is
down.
How is that fixed?
it shows
version: cluster: port: status: etc.

Port is correct status shows down.

When I go to initialise PostgreSQL, it goes no further.
