Normally, you would have a DHCP server, perhaps included in your
router, which would hand out local IP addresses.

Possible cause 1: you don't. 

Possible cause 2: you do, but it is full or configured not to
give this machine an IP.

Most likely cause: underlying networking is not working right.

Ethernet or wifi?

What does "ip l" tell you? "ip a", too.
