Title:
  Can't boot installer off PXE server

Status in ubiquity package in Ubuntu:
  Won't Fix

Bug description:
  Please excuse if ubiquity is not the appropriate module.

  1) 20.04
  2) n/a
  3) Expected result: 20.04 can be booted just like 18.04 off a PXE server
  4)

  Scenario:
  ubuntu 20.04
  I copied all the files from /casper to a directory on a PXE server, the relevant part in pxelinux.cfg is

  
  LABEL u200464lts
  KERNEL  u200464/casper/vmlinuz
  APPEND root=/dev/nfs/ boot=casper netboot=nfs nfsroot=192.168.100.205:/sda5/misc/netboot/u200464 initrd=u200464/casper/initrd  --

  I boot a machine using PXE, select the abovementioned entry.
  screenn output:

  Loading vmlinuz...
  Loading initrd..
  ..

  boot process continues to

  
  Begin: Running /scripts/casper-premount ... done.
  done.
  Begin: Trying netboot from 192.168.100.205:/sda5/misc/netboot/u2004 
  connect: Network is unreachable
  NFS over TCP not available from 192.168.100.205

  this is repeated until a busybox is shown

  All file permissions are set to 444

  
  Using 18.04 

  This is the relevant part of pxelinux.cfg

  LABEL u180464
  KERNEL  u180464/casper/vmlinuz
  APPEND root=/dev/nfs/ boot=casper netboot=nfs nfsroot=192.168.100.205:/sda5/misc/netboot/u180464 initrd=u180464/casper/initrd  --

  ...and everything is working fine, after 
  Begin: Running /scripts/casper-premount ... done.

  the network interface is configured.
