[Bug 1851311] Re: Grub 2.04 Out of memory error, No server error

[Benoit THIBAUD]

https://savannah.gnu.org/bugs/?57322 is the bug on the development team
site..

This menu works for me
menuentry "...       Gparted live" {
	set isofile="/isos/gparted-live-0.33.0-1-amd64.iso"
	search --set=root --file $isofile
	loopback loop $isofile
	linux (loop)/live/vmlinuz boot='live' union='overlay' username='user' config locales='fr_FR.UTF-8' keyboard-layouts='fr' components noswap noeject toram='filesystem.squashfs' ip='' findiso="${isofile}"
	initrd (loop)/live/initrd.img
}

but the xubuntu's ones don't..

Title:
  Grub 2.04 Out of memory error, No server error

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  Trying to loop mount ISO.

  Installed grub 2.04 to flash drive in UEFI mode from 19.10
  Flash drive does not boot and gives Out of memory error & no server error. Must load kernel first.

  Re-installed grub from 18.04 to same flash drive using same boot stanza.
  Booted without issue.

  From 18.04
  fred at Bionic-Z170N:~$ grub-install -V
  grub-install (GRUB) 2.02-2ubuntu8.13

  from 19.10
  fred at fred-Z170N-eoan:~$ grub-install -V
  grub-install (GRUB) 2.04-1ubuntu12

  Boot stanza that works in 2.02 but not in 2.04

  menuentry "Focal Live ISO" {
  set isofile="/ISO/focal-desktop-amd64.iso"
  loopback loop (hd0,1)$isofile
      linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile toram noeject
      initrd (loop)/casper/initrd
  }
