CRITICAL bgp-agent [-] Unhandled error: AssertionError

[satishdotpatel]

Hi,

I am following your blog to create my lab the way you did here https://ltomasbo.wordpress.com/2021/02/04/ovn-bgp-agent-testing-setup/ but i am using Ubuntu 20.04 instead of CentOS8 which is dead and hard to install devstack.

Everything went well but i stuck here when installing bgp-agent

$ python3 setup.py install

Encounter following error when i execute bgp-agent

root@rack-1-host-2:/usr/local/bin# bgp-agent
