with newton, manually installed, when I start the neutron agent for openvswitch (on network node and/or compute nodes), the service fails, only saying "uncaught exception".

We spent weeks to diagnos this problem. yes weeks...

If I override LANG to C in systemd unit files it works !!!

Seems a subcommand in some python librairies is waiting for "Exit code" in stdout, but on my system we have "Code de sortie" instead (french here). Is that a known bug ?

Best regards,

Edouard
