Oracle Cloud Ubuntu Instance has no public ip?

Question

I just sign up an oracle free tier account and create a Ubuntu instance. But it does no have a public ip.

Primary VNIC Information
Private IP Address:10.0.0.2
Internal FQDN:instance-20191003-0043...ShowCopy
Public IP Address:Unavailable
Subnet:Public Subnet
Network Security Groups:
None

I looked around and asked oracle customer service, but they said they have no support to Ubuntu :(

By default, Ubuntu Instances does not have a Public IP assigned. Upon creating your Instance on Configure Networking Section of Create Compute Instance Page choose "Assign a Public IP address" radio button (located at the bottom).
