Installed ryu on Ubuntu22.04. Trying to run the simple-switch-13 application:
student@uc3m:~$ ryu-manager ryu.app.simple_switch_13

after fixing with the requirements generated on a working Ryu on Ubuntu 20.04
It's because this project not support for python 3.10, use python 3.9 or previous version may be useful, in my ubuntu I choose install anaconda to manager multi python version.
@paaguti i saw you created a PR to a fork with this working in 22.04. i followed your instructions but it's still not working (different error related to module 'collections'). any suggestions to make this continue to work?
ah, possibly just need to add dnspython==2.2.1 to pip-requires
Here's how I got it working:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get install virtualenv python3.9 python3.9-distutils
#create the virtualenv
virtualenv -p`which python3.9` ryu-python3.9-venv
source ryu-python3.9-venv/bin/activate
echo $VIRTUAL_ENV #check if we are indeed in the virtual environment
pip install ryu
pip uninstall eventlet
pip install eventlet==0.30.2
ryu-manager --help
My fork now works with Python3.10+

how did you got it working? are you following the @jachermocilla steps or any other ways?
So I guess the PR won't be merged until a new maintainer is found?

hey Paaguti! I just tried out the latest Ryu, but seems another error appears. I wonder if you familiar with this error when testing ryu?
