OK, based on the list of packages provided by Scott Lewin, I uninstalled network-manager, network-manager-gnome and ubuntu-desktop (since ubuntu-desktop depends on network-manager) from my computer, rebooted and... the network interface is coming up fine! i tried to reboot a second time, once more it worked OK. Then I reinstalled it and it doesn't work again. So the problem comes from network-manager.
** Changed in: Ubuntu Sourcepackagename: None => network-manager -- internet connection will not automatically connect after last update https://launchpad.net/bugs/92299 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
