Comment 5 for bug 1969970

Hi, I just ran into exactly this problem with the 22.04.3 ISO freshly downloaded today. I copied the same NFS-based PXE-boot configuration as I used for 20.04:

        MENU LABEL Ubuntu 22.04 x64 LTS Server
        KERNEL installroot/Ubuntu/22.04/server/casper/vmlinuz
        APPEND boot=casper netboot=nfs nfsroot=192.168.1.12:/srv/pxe/installroot/Ubuntu/22.04/server initrd=installroot/Ubuntu/22.04/server/casper/initrd toram ip=dhcp root=/dev/nfs
        TEXT HELP
        Boot Ubuntu 22.04 x64 LTS Server
        ENDTEXT
        MENU LABEL Ubuntu 20.04 x64 LTS Desktop
        KERNEL installroot/Ubuntu/20.04/desktop/casper/vmlinuz
        APPEND boot=casper netboot=nfs nfsroot=192.168.1.12:/srv/pxe/installroot/Ubuntu/20.04/desktop initrd=installroot/Ubuntu/20.04/desktop/casper/initrd toram ip=dhcp
        TEXT HELP
        Boot Ubuntu 20.04 x64 LTS Desktop
        ENDTEXT

I added 'root=/dev/nfs' and it didn't help. However, adding 'ignore_uuid' did allow it to progress and start booting. Does sound like there's an issue with Casper here.

Cheers,
Rob J
