Don't know why it cannot find mn.
Are you running as root user? May be try non-root and use sudo.

Does "sudo minindn" also fail?
You are using Mininet from github source, right?(https://github.com/mininet/mininet)

Can you please detail the steps you followed to install Mininet?
Can you also go to the Mininet folder and try:sudo ./util/install.sh -nvand see if there are any errors?

The kernel might be missing some modules. Use Vagrant ubuntu/trusty64 template, which is known to work properly.

Hello All,
I've tried to install mini-ndn by following steps in https://github.com/named-data/ mini-ndn/blob/master/INSTALL.m d
and in one aspect, it requires installing mini_net,
again I follow the exact steps stated but when I try to use 
sudo mn --test pingall
to see if it works well...
I encounter this error:
Exception: Error creating interface pair (h1-eth0,s1-eth1): RTNETLINK answers: Operation not supported
do you have any idea how can I handle it? Sepehr Abdous
