Can you please also provide an example for a file that doesn't properly get modified?
I've been testing this, but on my system the /etc/network/interfaces file gets properly commented for inet6 entries as well, even without your changes. My tests were done with the following settings: auto eth0 iface eth0 inet dhcp iface eth0 inet6 dhcp auto Granted, there were no additional settigns for the inet6 stanza. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1005091 Title: NetworkManager does not manage device after install on IPv6 network Status in “network-manager” package in Ubuntu: Confirmed Bug description: When installing Ubuntu Desktop 12.04 with debian-installer on a network with IPv6 enabled, NetworkManager disabled network interfaces from automatically configuring via DHCP in /etc/network/interfaces, but does not disable them from automatically configuring IPv6. This prevents NetworkManager from taking over control and managing the network interface because it still appears to be maintained by the ifupdown, but has IPv4 disabled from configuring at all. The resultant /etc/network/interfaces file looks like this: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 #NetworkManager#iface eth0 inet dhcp # This is an autoconfigured IPv6 interface iface eth0 inet6 auto Because there is a non-commented iface line for eth0, NetworkManager never takes over management.
