The URL is changed intentionally, to notify all users that these images are deprecated and will not be updated after 20.04.0 GA, and will no longer be published in the future.
You should not be using virt-install, and simply boot the s390x cloud- image in-place, with suitable cloud-config drive attached. This way, you simply directly boot into installed ubuntu server, which executes cloud- init and reconfigures the instance on first boot as desired without performing installation & reboot. If you want to test the installer, please use the new installer interactively or with auto-install config provided as a cloud-config drive as mentioned on the download page itself http://ports.ubuntu.com/dists/focal/main/installer-s390x/current/legacy- images/ We felt that we had to rename and change URLs, to notify all automated systems that these images are going away. This communication / notification mechanism seems to be working as intended.

See virt-install man page for various distro examples. Looking at previous releases I would guess it expects an "images" directory instead of the new "classic-images" directory. I'm aware of the workaround to specify kernel/initramfs directly but that shouldn't be a solution. == Comment: #2 - Andre Wild1 <andre.wi...@ibm.com> - 2020-04-15 03:51:21 == (In reply to comment #0) > Installer version: Latest > https://ports.ubuntu.com/ubuntu-ports/dists/focal/main/installer-s390x > Sorry I've copied the wrong link.
