[Seiichi Nakashima]

Hi,

Today I download jammy-desktop-amd64.iso,
and boot up from grub, but same error displayed console forever.

line 49: can't open /dev/sr0: no medium found

and I could not Ctrl-C, I reset PC.

My /etc/grub.d/40_custom

menuentry "Ubuntu 20.04.4 ISO" {
    set isoimg="/iso/ubuntu-20.04.4-desktop-amd64.iso"
    loopback loop (hd1,msdos1)$isoimg
    linux (loop)/casper/vmlinuz boot=casper toram iso-scan/filename=$isoimg
    initrd (loop)/casper/initrd
    }

menuentry "Ubuntu 22.04 ISO" {
    set isoimg="/iso/jammy-desktop-amd64.iso"
    loopback loop (hd1,msdos1)$isoimg
    linux (loop)/casper/vmlinuz boot=casper toram iso-scan/filename=$isoimg
    initrd (loop)/casper/initrd

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

https://releases.ubuntu.com/22.04.3/ is a link to the current ISO for the 'jammy' release
Is your bug report still relevant when using that ISO?
