Ryu-manager crash on Ubuntu 22.04 (Python3.10.4)

[paaguti]

Installed ryu on Ubuntu22.04. Trying to run the simple-switch-13 application:

student@uc3m:~$ ryu-manager ryu.app.simple_switch_13

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]

Thanks, I went for virtualenv directly... ;-) the hard way :-) /PA

@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?

[PatrickTague]

ah, possibly just need to add dnspython==2.2.1 to pip-requires

[paaguti]

Thx, I'l try, but I haven't had any crashes up until now... /PA

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

[paaguti]

My fork now works with Python3.10+

how did you got it working? are you following the @jachermocilla steps or any other ways?

[paaguti]

Nope, I started dissecting problems and updating dependencies... a hell of a work. Currently looking at 3.11 ...

So I guess the PR won't be merged until a new maintainer is found?

[paaguti]

Don’t know if there ever will be. That’s why I forked…Enviado desde mi iPhoneEl 15 ago 2023, a las 21:05, Patrick Dumais @.***> escribió: 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?
