Package: debian-edu-router-config Version: 2.12.7 Currently network configuration fails if interfaces are already configured in /etc/network/interfaces, that is debconf will complain that there are leass than two network interfaces in unconfigured state and only offer to skip this step. As this usually happens right after installation of the package this is very inconvenient.
If there is no configuration in /etc/network/interfaces but any interface is configured and up debconf will proceed, generate configuration in /etc/network/interfaces.d but fail to restart networking.service and delete the new configuration again (see attachment). IMHO a reasonable solution would be to present a warning at the beginning, then bring down/flush the interfaces which are to be configured, and remove their configuration stanzas from /etc/network/interfaces. -- Guido Berhoerster
