[Bug 1910568] Re: Ubuntu 18.04 Desktop installation through nfs fails during copying files with SQASHFS errors

[Sebastien Bacher]

Thank you for the bug report, those errors usually hints of a corrupted
image, could you try downloading it again and verify that the checksum
is correct?

Title:
  Ubuntu 18.04 Desktop installation through nfs fails during copying
  files with SQASHFS errors

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  Tried to install Ubuntu
  DISTRIB_ID=Ubuntu
  DISTRIB_RELEASE=18.04
  DISTRIB_CODENAME=bionic
  DISTRIB_DESCRIPTION="Ubuntu 18.04.5 LTS"

  trough PXE boot and NFS:

  label install2
  menu label ^Install XUbuntu 18.04 Desktop NFS
  menue default
  kernel ubuntu1804/vmlinuz
  append initrd=ubuntu1804/initrd boot=casper netboot=nfs nfsroot=192.168.200.1:/var/lib/nfs/ubuntu1804/desktop  ide=nodma acpi=off

  (also tied w and w/o ide=nodema and/or acpi=of)

  PXE Server:
    VM Xubuntu 18.04.5 LTS
    Network bridged 

  Client:
    VM should become Ubuntu 10.04.5 LTS :(
    Network bridged 

  Hypervisor:
    both VMs run as virtualbox VM
    Virtualbox version 6.1.16

  Host:
    Ubuntu 20.04.1 LTS

  
  I get the Desktop and start "Ubuntu 18.04.5LTS Installation", select keyboard, location and clear disk completely .... and start.
  The disk is going to be parted and mounted, the file copy starts succcessfully.
  Ca. after 75-80% progress the copy process stops with a error message regarding read from CD/DVD  issues.
