I'm thinking it has to be related to hardware or the kernel module of eth0. I have 3 PC's running identical software (Kubuntu Precise complete up to date): - 1 older laptop - 1 older desktop - 1 brand-new laptop
The install was for all three a clean install: no upgrade from the previous release. The home directories were of course preserved. Only the brand-new laptop has problems. For the others is managed=false in NetworkManager.conf and network/interfaces only contains auto eth0 and eth0 comes up properly. To make the thing even more strange: the brand-new PC was previously running lucid-i386 with the backported oneiric kernel (because the driver for eth0 was not supported by the lucid kernel) and then the settings were managed=false in NetworkManager/nm-system-settings.conf and eth0 was not mentioned at all in /etc/network/interfaces. eth0 did in lucid connect without problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1018933 Title: NetworkManager does not connect eth0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1018933/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
