Hi,
Since I installed the version 1.10.2-13 of NetworkManger I cannot start my network.
Here are the error logs :
NetworkManager[31994]: <warn> [1529604114.4607] platform-linux: do-add-ip4-address[2: Y.Y.Y.Y/24]: failure 22 (Argument invalide)
NetworkManager[31994]: <warn> [1529604114.4608] platform: route-sync: failure to add IPv4 route: 0.0.0.0/0 via X.X.X.X dev 2 metric 100 mss 0 rt-src user: Le réseau n'est pas accessible (101); is the gateway directly reachable?
systemd[1]: network.service: control process exited, code=exited status=1
systemd[1]: Failed to start LSB: Bring up/down networking.
systemd[1]: Unit network.service entered failed state.
systemd[1]: network.service failed.
...where Y.Y.Y.Y is the IP address of the server, and X.X.X.X is the gateway.
The latest version 1.10.2-14 didn't correct the problem neither.
If I downgrade to the version 1.8.0-11 of NetworkManager everything work well.
Some sugguest to disable NetworkManager service and only use Network service. But it's only a workaround; NetworkManger should work like it does with the oldest versions.
Thanks for your help.
