After performing some additional testing, the problem only occurs with the edgy alternate install and not with the desktop install. During the alternate install, the following message appears:
[!] Configure the network No network interfaces detected No network interfaces were found. The installation system was unable to find a network device. You may need to load a specific module for your network card, if you have one. For this, go back to the network hardware detection step. So, this is most likely what prevents the network controller from being configured properly in the interfaces file. Also note that the desktop install failed once with the following message: BUG: soft lockup detected on CPU#0! This is the same problem logged in Bug #80502. However, the problem didn't happen during subsequent attempts of the edgy desktop install. -- Realtek ethernet controller detected but no automatic dhcp on edgy https://launchpad.net/bugs/81782 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
