Init problems after install for the proof-of-concept scenario - Missing Step?

*** UPDATE***
Hello All,

I’m reinstalled the Ubuntu and began the MAAS install, I’ve now been able to to make it beyond the following steps:

Command:
sudo snap install --channel=3.2/beta maas
sudo snap install maas maas-test-db
sudo maas init region+rack --database-uri maas-test-db:///
