Reading the log file that Stephan supplied... First we see three cases of successful connection.
May 8 14:12:32 d-charms NetworkManager: <info> (eth0): carrier is OFF May 8 14:12:32 d-charms NetworkManager: <info> (eth0): new Ethernet device (driver: 'r8169') May 8 14:12:32 d-charms NetworkManager: <info> (eth0): exported as /org/freedesktop/NetworkManager/Devices/0 May 8 14:12:32 d-charms NetworkManager: <info> (eth0): now managed May 8 14:12:32 d-charms NetworkManager: <info> (eth0): device state change: 1 -> 2 (reason 2) May 8 14:12:32 d-charms NetworkManager: <info> (eth0): bringing up device. [...] Then three cases, on the date that Stephan said things stopped working, where NM does nothing further with eth0 than the following. May 9 23:07:08 d-charms NetworkManager: <info> (eth0): carrier is OFF May 9 23:07:08 d-charms NetworkManager: <info> (eth0): new Ethernet device (driver: 'r8169') May 9 23:07:08 d-charms NetworkManager: <info> (eth0): exported as /org/freedesktop/NetworkManager/Devices/0 There is no reboot between the first group and the second group. Stephen: What happened between May 9 18:19:15 and May 9 23:07:08? Did you upgrade network-manager? ** Summary changed: - Regression: NetworkManager stopped managing eth0 even though it's not defined in /e/n/i + NetworkManager fails to manage eth0 even though "iface eth0" is not defined in /e/n/i -- r8169 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/578012 Title: NetworkManager fails to manage eth0 even though "iface eth0" is not defined in /e/n/i -- r8169 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/578012/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
