[Bug 1616400] Re: Lubuntu's alternate i386 installer cannot connect to a network

[Martin Pitt]

FTR: current netcfg design is that it wipes the generated ifupdown
config if NetworkManager is installed, so the duplicate run (where the
second one creates an essentially empty ifupdown file) is intended. It
just needs to install a netplan policy corresponding to
http://bazaar.launchpad.net/~ubuntu-core-dev/livecd-
rootfs/trunk/view/head:/live-build/auto/build#L196 to unblacklist
ethernets from NM.

Title:
  Lubuntu's alternate i386 installer cannot connect to a network

Status in debian-installer package in Ubuntu:
  In Progress
Status in netcfg package in Ubuntu:
  Fix Committed

Bug description:
  Running Lubuntu's Yakkety alternate i386 beta1 installer fails.

  I arrive at a red screen with the text: "No network interfaces were
  found ..."

  This is in a Toshiba laptop, that I have used for testing since 2013,
  and it works with the corresponding current Lubuntu desktop iso files.
  I expect the wired ethernet to work with the alternate iso file like
  it worked, when I tested with Yakkety alternate i386 alpha 2.

  pro-c850-19w/

  ctrl + alt + F4 shows the following log text:

  -----
  main-menu: menu item 'ethdetect' selected
  net/hw-detect.hotplug: detected hotpluggable network interface lo

  ...

  netcfg: WARNING: **: Couldno't read Wpasupplicant pid file, not trying to kill.
  netcfg: INFO: Could not find valid BOOTIF= entry in /proc/cmdline
  -----

  It works to continue the installation without network. The installed
  system boots, but the installed system fails to connect to the
  internet. I have not tried to fix it, just noticed that ethernet does
  not work 'out of the box' as it should in the installed system.
