Bug Description

Not sure where to put this bug, but I'll start here (apologies). I'm not actually sure if it's a bug or intended behavior, but if it's intended, it would be nice if the files the installer places down include better comments (or simply delete the no-longer-relevant file).

I installed Bionic using mini.iso and selected Ubuntu Desktop.

It seems that two Netplan configurations are generated; it's not clear if this is correct, and it's not clear which configuration takes precedence. It looks like NetworkManager eventually took control of the interface, as seen below:

mpontillo@bionic:/etc/netplan$ ls -l

-rw-r--r-- 1 root root 194 Nov 10 19:25 01-netcfg.yaml
-rw-r--r-- 1 root root 104 Nov 10 19:36 01-network-manager-all.yaml

mpontillo@bionic:/etc/netplan$ cat *

Nice catch. This is a bug in netcfg, reassigning.
