Comment 0 for bug 1881163

I installed microstack into a fresh Ubuntu 20.20 following the instructions at:
   https://microstack.run/docs/

Install command:
    sudo snap install microstack --classic --beta

Then I ran microstack.init:
    sudo microstack.init --auto

I got the following output:

2020-05-28 18:55:16,534 - microstack_init - INFO - Configuring networking ...
2020-05-28 18:55:18,421 - microstack_init - INFO - Setting up ipv4 forwarding...

2020-05-28 18:55:19,978 - microstack_init - INFO - Waiting for RabbitMQ to start ...
Waiting for 10.20.20.1:5672

This hung for 20 minutes and so I hit cntrl-C.

My ips after the failed init are:
