This bug is affecting me as well on a fresh install of Ubuntu 10.10 x64. I find that I can get eth0 to connect by using two terminal windows.
In the first terminal window I type: $ sudo dhclient While this command is executing, in the second terminal window, I type: $ sudo service network-manager restart This causes the dhclient command to print out "receive_packet failed on eth0: Network is down" in between the lines of "DHCPDISCOVER...", but eth0 becomes active. (I am going to try Mathieu Trudel's suggestion and see if the issue goes away after reboot...) -- [Maverick] Auto eth0 not working after latest package upgrade https://bugs.launchpad.net/bugs/635475 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
