after installation, nm reports eth0 as a not managed network device

Hi Jean-Baptiste,

This is expected behaviour when eth0 is configured in /etc/network/interfaces. However, while the device shows as "not managed", you should still see applications as aware they are online (for instance, Evolution should be able to get online to retrieve mail without clicking "Work offline", and empathy should connect without issues as well).

Could you please verify this?

Thanks.

It appears to be an issue specific to the alternate CD. First guess says this is something done differently in netcfg, but I haven't looked at all yet.

As another option, we could start using the ifblacklist script in NM to change /etc/network/interfaces when NM is installed (and revert when it's removed).

The network card if up and listed in ifconfig and an IP address is associated.
My point is that with the desktop image the user is able to manage the wired interface with network manager and not with an installation from an alternate image. In this case eth0 is filled in /etc/network/interfaces.

Changelog

netcfg (1.62ubuntu1) oneiric; urgency=low

  * Resynchronise with Debian. Remaining changes:
    - Set default hostname to 'ubuntu'.
    - Drop priority of netcfg/get_domain to medium for non-static
      configurations.
    - Use 'auto <interface>' for all interfaces, dropping allow-hotplug
      which doesn't work with current udev.
    - Call /usr/lib/network-manager/ifblacklist_migrate.sh from
      finish-install if present, so that 'auto dhcp' interfaces are disabled
      if network-manager is in use. May be preseeded away with
      netcfg/network-manager.

So it's really an issue in network-manager, seems like we're dropping ifblacklist_migrate.sh now.

To avoid an unnecessary delta with Debian, I'll keep ifblacklist_migrate.sh installed in /usr/lib/NetworkManager instead of /usr/lib/network-manager, this means we'll also need a small update to netcfg.

This bug was fixed in the package network-manager - 0.8.9997-1ubuntu2

---------------
network-manager (0.8.9997-1ubuntu2) oneiric; urgency=low

  * debian/rules: re-install ifblacklist-migrate.sh so installs from the
    alternate image correctly factor out devices managed by NetworkManager.

I believe that this may still be an issue with the mini.iso image. I installed 11.10 to my Dell mini 9, using the mini.iso image and used a wired connection to download the install packages etc. Afterwards, my /etc/network/interfaces config had eth0 listed and nm was unable to manage the connection.

I removed the eth0 lines from the config file, restarted the network-manager service and everything seemed to work much better.

FTR, I initially noticed I had a problem because my netbook would show messages indicating that it was 'waiting for network connection' during bootup.

Cheers!
