unable to use applications like hub through pox controller

[SibasisRath]

Hello murphy I am new to this SDN topic I installed ubuntu 14.04 server distribution in my virtual box and upon that I installed ubuntu desktop. I am trying to use pox controller. I installed it successfully by cloning its source GitHub repository. I am now inside pox directory where I used a command ./pox.py pox.forwarding.hub to run the SDN hub application but it is showing error

Traceback (most recent call last): File "./pox.py", line 43, in from pox.boot import boot File "/home/mininet/pox/pox/boot.py", line 41, in import pox.openflow File "/home/mininet/pox/pox/openflow/init.py", line 38, in from. import libopenflow_01 as of File "/home/mininet/pox/pox/openflow/libopenflow_01.py", line 25, in from pox.lib.packet.packet_base import packet_base File "/home/mininet/pox/pox/lib/packet/init.py", line 27, in from . import arp as ARP File "/home/mininet/pox/pox/lib/packet/arp.py", line 41, in from .ipv4 import ipv4 File "/home/mininet/pox/pox/lib/packet/ipv4.py", line 48, in from .gre import * File "/home/mininet/pox/pox/lib/packet/gre.py", line 43, in from . import ipv4 ImportError: cannot import name 'ipv4'

So, I tried to do the exact thing by installing mininet VM and it worked properly. So, I am not able to understand why it happened in that case and can you suggest any solution for this

Before this traceback, is there any POX log? If so, can you post it? Also, you said you cloned from github... but which version/branch?

(Also, 14.04 is eight years old! Is there a reason to use such an old version?)

Closed due to lack of followup.
