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.
Performing 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.
