I want to use Kytos with Mininet based on this document. I get this error when I try to Ping.

• mininet:

• kytosd logs:

You should try kytos-ng (https://github.com/kytos-ng/kytos), a fork from the original Kytos SDN Project (https://github.com/kytos/). Check it out, if you get the same error using kytos-ng and reopen this issue there.

@majidmc2, kytos-ng tutorials docs is still in progress, however the page that documents how to setup the environment is updated, Python 3.9 is the current supported main version now, also OpenFlow 1.0 will be deprecated, of_l2ls works with OpenFlow1.3. The rest of the tutorial docs will likely be updated soon. In the meantime, if you need help you can also join kytos-ng Slack workspace.

@josemauro, appreciated your help :)
