I have the same problem on two independent systems with Ubuntu 15.04. 32bit and 64bit
The NetworkManager.service dies after switching from WLAN to Wired Lan, with the following message: NetworkManager.service - Network Manager Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled; vendor preset: enabled) Active: failed (Result: signal) since Mo 2015-09-21 21:15:19 CEST; 17min ago Sep 21 21:09:59 NOTEBOOK NetworkManager[658]: <error> [1442862599.112057] [platform/nm-linux-platform.c:1714] add_object(): Netlink error adding ff11:1111:2222:3333:444:5555:6666:affe/64 lft 3645se...address family My solution: restart the service with: systemctl restart NetworkManager -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1461015 Title: Wired disconnects due to add_object(): Netlink error adding 0.0.0.0/0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1461015/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
