I know nothing about LXDE (or other DEs). > It has never had any interface named eth0.

I would have expected a response more like: $ aptitude why apt-file Manually installed, current version 3.2.2, priority optional No dependencies require to install apt-file $ but I guess the Provides has some influence. Both ifupdown2 and netscript can be used instead of ifupdown, though the latter is for a more specialised scenario. It's always possible that ifupdown was installed as an alternative to connman, which is also in the Live image. I don't know which gets started by default, either in Live, or the subsequent installation from Live. > Why openresolv wouldn't work? That doesn't parse, and without any context, I don't know what it means. Cheers, David.
