Hi, By the traceback you are quite close to master. The issue you see is really strange. I would try to debug it manually, like starting a python shell and doing the same import and playing with the pythonhome for example as it was suggested. I usually use Ubuntu20 for my test envs and never seen such issue with devstack. Regards Lajos mahdi n <m73hdi@gmail.com> ezt írta (időpont: 2022. szept. 5., H, 17:32):

I was installing DevStack on Ubuntu 20.04 when I encountered this error It says that the Neutron module was not found while neutron is installed

++lib/neutron_plugins/ovn_agent:filter_network_api_extensions:439

...

/usr/local/bin/python3.8 -c 'from neutron.common.ovn import extensions ;\

print(",".join(extensions.ML2_SUPPORTED_API_EXTENSIONS)) ' Traceback (most recent call last):
