I just installed ubuntu server 14.04 LTS, overwriting 12.04.
The installation appears to proceed correctly. During the installation process the IP and hostname are correctly obtained via dhcp. However, when installation completes and the machine reboots (removing the disc from the drive), the selected interface,
eth0 does not obtain the IP.
sudo ifdown eth0 && sudo ifup eth0 and
sudo dhclient -v eth0 both result in a bunch of
DHCPDISCOVER messages and errors with:
No DHCPOFFERS received. No working leases in persistent database
/etc/network/interfaces (untouched following fresh installation)
auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
The interface and cable were working fine with the previous ubuntu server 12.04 installation. Any ideas on what to do? This is a fresh install, and doesn't obtain the IP immediately after the reboot initial reboot.
