i386 install ubuntu server (netboot image, from usb): no wired network after install [incorrect name in interfaces file]

[Redmar]

After installing installing ubuntu server via the netboot image I get no (wired) internet connection on this hardware: https://launchpad.net/+hwdb/+fingerprint/b845c366ea09c60efa3a45c1b5b21525

Please let me know what other information you need to investigate this further.

The problem appears to be that my wired network device is seen as 'em10' during the installation, but as eth0 after the install.

I've attached the relevant lines from /etc/network/interfaces

[Redmar (redmar)]

I've just done a netboot install of kubuntu, it has working network after reboot and the following lines in /etc/network/interfaces:

auto lo
iface lo inet loopback

# The primary network interface
#NetworkManager#auto em10
#NetworkManager#iface em10 inet dhcp

Ah. This is a new feature, not a bug =)

Please change this bug to confirmed or file a new bug if there is something missing from the ubuntu-devel instructions.

OK, so the name in the file is correct - but the network name doesn't match - why?

Questions:
  1) Did you preseed?
  2) What's your pxe config
  3) Is the biosdevname package installed ? If it isn't then what happens if you install it - does it pick the right name up?

I'm suspecting the problem is biosdevname hasn't been installed, and hence it doesn't get renamed to em10.

1) No, I just used the default latest build for netboot, found here http://iso.qa.ubuntu.com/qatracker/milestones/219/builds/21555/downloads
2) I don't think I'm using pxe, I'm installing from usb with the image linked in 1)
3) biosdevname was not installed, but installing it and rebooting did not solve the problem.

I'm also marking the bug as confirmed since I'm not doing a preseeded installation, so afaik, the ubuntu-devel instructions do not apply.

Ah ok - so the title is a bit wrong; you're not actually netbooting, you're just using the netboot image locally
