This is going to be a casper and/or livecd-rootfs issue, so reassigning.
What I don't understand is that neither the blkid output nor the contents of /cdrom/.disk/casper-uuid-generic appear to match what I have here:
$ blkid ~/devel/iso/ubuntu-22.04-live-server-amd64.iso
/home/vorlon/devel/iso/ubuntu-22.04-live-server-amd64.iso: BLOCK_SIZE="2048" UUID="2022-04-21-06-14-25-00" LABEL="Ubuntu-Server 22.04 LTS amd64" TYPE="iso9660" PTUUID="c84e0225-4be7-447a-9fa1-ebf040bdc01f" PTTYPE="gpt"
$ cat /mnt/.disk/casper-uuid-generic
ba2335f2-81b6-46b2-a037-549fe52a8261
$
I don't know how blkid is figuring a UUID for an iso9660 filesystem, but here it is the timestamp of the image on the server, which is preserved by wget. It's surprising that yours has a timestamp months in the past...
