When rebooting after the updates finished, it gave a prompt saying “Waiting for server network configuration...” which was followed by “Waiting up to 60 more seconds for network configuration...” and then, about 60 seconds later, “Booting system without full network configuration...”. And that was accurate: the eth0 network was missing. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>When I set up the computer, I had moved eth0 out of /etc/network/interfaces and had set it up via the Settings -> Network Connections tool so I could set it up with DHCP. But after the update, the Network Connections tool wasn’t working – it wouldn’t show me eth0 at all. I put eth0 back into the /etc/network/interfaces file and rebooted and confirmed that the network jack was working fine (albeit now with DHCP instead of the IP I had set in Network Connections). I booted up and switched the kernel on boot to the version prior to the update today and it booted fine and the network worked fine. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Figuring that something might have gone wrong with the install of the new kernel version, I tried reinstalling the new kernel with (network was able to connect to Internet because of adding eth0 to /etc/network/interfaces):<o:p></o:p></p><p class=MsoNormal> sudo apt-get install --reinstall linux-image-3.13.0-36<o:p></o:p></p><p class=MsoNormal>As a result, it installed 3.13.0-36-lowlatency – what? Lowlatency? I didn’t ask for that. Well, regardless, that new install added to my bootlist and became default and didn’t help the networking issue. So I removed it with:<o:p></o:p></p><p class=MsoNormal> sudo apt-get remove linux-image-3.13.0-36-lowlatency<o:p></o:p></p><p class=MsoNormal>and then removed the kernel that installed during the software update earlier:<o:p></o:p></p><p class=MsoNormal> sudo apt-get remove linux-image-3.13.0-36-lowlatency<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>After putting back my xorg.conf that got moved during the kernel upgrade and removing eth0 from /etc/network/interfaces, all is well again with kernel 3.13.0-35. I am posting here so that anyone else that is thinking about updating their kernel via software update may want to do a backup before proceeding. And if anyone wants to weigh in with what might have gone wrong with this latest kernel and Network Connections, that might help others too. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Although in all likelihood this is a general Ubuntu issue, there are enough of us running Mythbuntu and using Network Connections that it warranted posting here. Also, in case it matters, I have a Ceton PCI card installed in the system that is also using the Networking interface. I have changed my Software Update settings so that it won’t suggest such updates again! <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Ken.<o:p></o:p></p></div></body></html>
