Comment 125 for bug 1922342

Hi,

the fix for #1977644 does not solve the problem of #1922342. It only reduces
the need for ISO patching to a single operation which can be done on the
ISO image file before putting it onto a USB stick (and not a second time
directly on /dev/sdX after the first boot):

  # Patch the ISO already as image on hard disk
  ISO=ubuntu-22.04-desktop-amd64.iso
  dd if=/dev/zero bs=1 count=16 of="$ISO" conv=notrunc seek=462

I think that #1922342 can only be considered solved if the users of Ubuntu
ISOs can easily find this procedure and an explanation when it should be
applied.
My proposal would be to put a brief hint into
  https://ubuntu.com/tutorials/install-ubuntu-desktop#4-boot-from-usb-flash-drive
and to add a new page
  https://ubuntu.com/tutorials/remove-boot-flag-from-iso
which gives details.

The brief hint would be like:

  "On some very old and meanwhile rare machines it can last 8 minutes or
   longer until you see this welcome screen.
   If you plan just a single installation then simply wait until the screen
   appears.
   But if you plan to repeatedly use the "Try Ubuntu" offer on such an old
   machine, then see [link to new page tutorials/remove-boot-flag-from-iso]
   for a way to substantially shorten this time span."

Does anybody here know how to contact the custodians of the tutorials ?

Have a nice day :)
