I upgraded from 16.04.3 (amd64) to 17.04 directly and stumbled on this problem. /usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf had the wrong configuration: [keyfile] unmanaged-devices=*,except:type:wifi,except:type:wwan setting unmanaged-devices=none in this file did the trick for me, but this is a error which IMHO needs to be fixed - the system is a Laptop with the normal Unity Desktop Environment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1658921 Title: NetworkManager does not manage wired connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1658921/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
