[Bug 1969970] Re: ubuntu jammy 22.04 iso: unable to find a live file system on the network

[Dan Bungert]

Would you confirm that the sha256 sum of the iso matches
https://releases.ubuntu.com/22.04/SHA256SUMS ?

I'm getting different results for the above commands.
The UUID there makes it look like you have a 2-month out of date iso.
Thanks!

# lsblk /dev/loop17 -J -O  | jq '.blockdevices[0] | .label, .uuid'
"Ubuntu-Server 22.04 LTS amd64"
"2022-04-21-06-14-25-00"

# cat .disk/casper-uuid-generic

Title:
  ubuntu jammy 22.04 iso: unable to find a live file system on the
  network

Status in casper package in Ubuntu:
  New

Bug description:
  I'm trying to pxe boot ubuntu jammy 22.04 iso from
  https://releases.ubuntu.com/22.04/ubuntu-22.04-live-server-amd64.iso,
  but it fails to boot with the error:

    unable to find a live file system on the network

  This problem can be worked around by setting the ignore_uuid kernel
  command line argument. But, I think we should not need to specify
  that, and maybe there's a problem with the UUID of the iso.

  I'm not sure if the helps, but blkid is returning:

  root at pxe:~# blkid 
  /dev/loop0: BLOCK_SIZE="2048" UUID="2022-02-17-11-56-08-00" LABEL="Ubuntu-Server 22.04 LTS amd64" TYPE="iso9660" PTUUID="949bae1b-adc7-4b27-be24-901c7c269b89" PTTYPE="gpt"

  
  And it seems the iso contains a different UUID:

  root at pxe:~# cat /cdrom/.disk/casper-uuid-generic 
  b897861a-11af-4ce6-88c1-b6ac2af8457b
