Ok, so these logs show that when you installed your machine, you had a single network interface, called eth0 at the time which was an Nvidia network card with MAC address: 00:0c:76:7e:fe:89
Nowadays, the only piece of nvidia hardware you seem to have is a graphic card. Your network cards now are: 00:17:31:a2:7d:55 00:17:31:a2:7f:ad You also once plugged a USB network card in this machine. So based on this, my guess is that you changed hardware in this machine quite significantly, resulting in the change of network cards. When you installed your machine, it was a AMD Athlon(tm) XP 3200+ but nowadays it's a AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ When you switched hardware, you should have changed /etc/udev/rules.d/70 -persistent-net.rules to match the new network hardware so that your new main network card would be assigned eth0 instead of eth1. The easiest way to do this, is my simply removing all the network interfaces from this file and rebooting, it'll then get populated again with the new values. If what I'm saying above sounds correct and the problem instead started appearing after the change of hardware, this isn't really a bug, it's actually the expected behaviour when moving an install to new hardware (network device names are linked to the MAC address to avoid them switching order between boots). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/900903 Title: "Waiting for network configuration" due to uncommented 'auto' lines in /etc/network/interfaces (historical installer/upgradebug?)
